Description
The IR11688 is a dual smart secondary-side controller IC optimized to drive two N-Channel power MOSFETs
configured for synchronous rectification in resonant converter applications. Each channel can drive one or multiple
parallel MOSFETs to emulate the behavior of Schottky diode rectifiers, bypassing the body diodes for the majority
of each conduction period to minimize power dissipation and remaining off during the blocking period.
The drain to source voltage of each rectifier MOSFET is sensed to determine the source to drain current and turn
each gate on rapidly at the start of each conduction cycle and off in close proximity to the zero current transitions
for each branch of the output rectifier circuit. Ruggedness and noise immunity are accomplished using an
advanced blanking scheme and double-pulse suppression that allows reliable operation in fixed and variable
frequency applications.
The programmable minimum on time (MOT) function provides flexibility to work over a wide range of switching
frequencies. The cycle-by-cycle MOT protection circuit is able to automatically detect a light or no load condition so
that the gate drives may be disabled to avoid unwanted reverse currents flowing through the MOSFETs.
The IR11688 has a wide Vcc supply voltage range from 4.75V to 18V, enabling its supply to be derived from the
output and eliminating the need for an auxiliary supply circuit in systems with output voltage as low as 5V.
The IR11688 also has very low quiescent current when the gate drives are not switching to offer minimal power
consumption in standby mode.

Detailed Pin Description
VCC: Power Supply
This is the supply voltage pin of the IC, monitored by the under voltage lockout circuit. It is possible to turn off the
IC entering UVLO mode by pulling this pin below the minimum turn off threshold voltage for micro power
consumption.
To prevent noise interfering with operation, a ceramic decoupling capacitor should be connected from Vcc to GND
and located as close to the IC as possible. A low value series resistor may also be added to the Vcc supply circuit
for filtering if required. Vcc is internally clamped at around 20V.
GND: Ground
This is power ground connection to the IC. Internal circuit blocks and gate drivers are referenced to this point.
MOT: Minimum On Time
The MOT programming pin controls the amount of minimum on time. Once VTH2 is crossed at either VD input, the
corresponding gate drive output will transition high to turn on the SR MOSFET. Spurious ringing and oscillations
can falsely trigger the input comparator to prematurely switch the output off. During the MOT period the input
comparator is disabled maintaining conduction through the MOSFET on for this preset minimum period.
The MOT is typically programmed between 500ns and 2us by means of an external resistor referenced to GND.
VD1 and VD2: Drain Voltage Sense
The VD pins are the voltage sensing inputs for the SR MOSFET drains. These are high voltage inputs therefore
particular care must be taken in properly routing the connections. Additional RC filters can be placed at these
inputs to improve noise immunity, however only a small resistor (≤1kΩ) and capacitor value (in the pF range) may
be used to avoid introducing excessive delay to the control input.
VS: Source Voltage Sense
This is the signal ground for the sources of the two SR power MOSFETs to provide an accurate differential voltage
measurement. Kelvin connect this pin to the source of MOSFET2 (channel 2 MOSFET) is recommended if the two
MOSFETs are far apart to each other.
GATE1 and GATE2: Gate Drive Outputs
Each gate driver output has +1A/-4A peak drive capability. Although these pins can be directly connected to the
SR MOSFET gates the use of gate resistors is recommended, especially when using several MOSFETs in parallel.
Care must be taken to keep the gate loop as short and as tight as possible in order to achieve optimal switching
performance.

UVLO/SLEEP Mode
The IC remains in the UVLO/SLEEP condition until the voltage at the VCC pin first exceeds the VCC turn on
threshold voltage, VCC ON. While in the UVLO/SLEEP state, the gate drive outputs are inactive and only a very small
quiescent current of ICC START is drawn. UVLO mode is accessible from any other state of operation whenever the IC
supply voltage condition of Vcc < VCC UVLO occurs. If during normal operation, the drain inputs remain inactive such
that no edges are detected for a period longer than TWAIT the IC enters SLEEP mode. It remains in a low power
state until woken up by a voltage transition at either VD input.
Normal Mode
The IC enters into normal operating mode when the VCC ON threshold has been exceeded. On entering Normal
Mode from the UVLO Mode the GATE outputs remain disabled until VDS transitions above VTH3 two times. This
ensures that the GATE output cannot be enabled in the middle of a switching cycle since this can cause undesired
reverse conduction. The cycle by cycle minimum on time (MOT) protection circuit also becomes activated to
prevent reverse currents occurring when conduction time is short, which may also happen during system power up
and down. The gate drives will continuously drive the MOSFETs after this startup sequence is completed.
MOT Protection Mode
If secondary current conduction time in either rectifier circuit branch is shorter than the set MOT, the subsequent
gate driver output pulse is skipped. This function avoids reverse current from occurring when the system is
switching at very low duty-cycles under very light or zero load conditions. The cycle by cycle MOT check circuit
always remains active in Normal Mode and MOT Protection Mode so that the IC will automatically resume normal
operation only after the load increases to a level where the secondary current conduction time exceeds MOT.
System standby power consumption is significantly reduced in this mode while the gate outputs are inactive.

General Description
The IR11688 dual SMART RECTIFIERTM controller is a high-voltage IC for synchronous rectification designed for
resonant converter applications. As stated, it emulates the operation of two diodes configured with a center tapped
transformer secondary by correctly switching on and off the synchronous rectifier MOSFETs in the two rectifier
circuit branches.
The core of this device consists of two high-voltage drain sensing inputs feeding high speed comparators to
differentially sense the drain to source voltage at each SR MOSFET. The SR MOSFET source to drain current is
detected from the voltage across the conducting body diode or the RDSON resistance when switched on. Internal
control logic allows the corresponding gate drive output to be switched on and off at the correct time to bypass the
body diode for the majority of the conduction period.
The IR11688 further simplifies synchronous rectifier control by offering the following power management features:
•
•
•
Wide VCC operating range allows the IC to be supplied from the converter output
Shoot through protection logic that prevents both GATE outputs from ever being high at the same time
Turn-off phase regulation to compensate for power device package inductance and avoid premature turn-
off
•
Optimized negative turn on voltage threshold detection and leading edge noise filter to minimize false
triggering due to ringing oscillations
The IR11688 control technique senses SR MOSFET source to drain voltages comparing them with three different
negative thresholds (VTH1, VTH2 and VTHR) to precisely control gate turn on and off as shown in figure 1:
VGATE
VTH2
VTH1
VTHR
VDS
Figure 1: Input comparator thresholds
Turn-on phase
When the conduction phase of each SR MOSFET begins, the device is off so therefore current starts to flow
through the body diode producing a negative VDS voltage across it. The body diode has a much higher voltage
drop than the one resulting from the MOSFET on resistance and is therefore sufficient to trigger the turn-on
threshold VTH2
.
When either VDS input remains below VTH2 for more than TBon (150ns), the gate of the corresponding SR MOSFET
is driven high, which causes VDS to reduce rapidly to ID x RDSON. The internal delay timer will be reset if VDS rises
above VTH2 before TBon times out. This turn-on blanking time helps to avoid misfiring that could be triggered by high
frequency ringing in DCM operation. The voltage drop at switch on is usually accompanied by some amount of
ringing, which could potentially trigger the input comparator to turn off the gate drive very quickly. However the
minimum on time (MOT) blanking period prevents this. The turn-on blanking time (TBon) and the MOT limit the
minimum conduction time for the secondary rectifiers determining the switching frequency upper limit that the
IR11688 may effectively operate at.
13

IR11688S
Regulation phase
After the gate has been driven high at switch on, the SR MOSFET remains on until the source to drain current falls
to the level where VDS reaches the regulation threshold VTHR. At the end of the MOT, the gate output is no longer
driven high and reverts to a high impedance state. When VDS<VTHR a weak pull down gradually discharges the
gate voltage held by the SR MOSFET input capacitance. As the gate voltage drops, the MOSFET channel
resistance increases as it enters the linear region. This causes VDS to once again exceed VTHR so that weak pull
down will cease until the conduction current falls to the point where VDS again drops below VTHR. This regulating
process continues so that the conduction period is extended until the current has fallen to a very low level. In this
way premature turn off, which can arise due to parasitic inductances in PCB traces and the MOSFET package, is
prevented. This period of conduction through the SR MOSFET body diodes is thereby reduced to a minimum
improving overall system efficiency.
Turn-off and reset phases
At the end of the switching cycle the conduction rectifier current reduces to zero so the VDS voltage will cross the
turn-off threshold VTH1. When this happens the gate is driven low to switch off the SR MOSFET. Any residual
current will again start flowing through the body diode causing a negative step in VDS. When this occurs VDS could
potentially trigger turn-on once again by crossing VTH2. To prevent this possibility, turn on is blanked for a time
period, tBLANK after turn off has occurred. The blanking time is internally set and can be reset only when VDS
crosses the positive threshold VTH3. Reset occurs only when VDS remains higher than VTH3 for more than the reset
blanking time, tBRST. This protects against false triggering due to ringing after the turn-off phase. Once reset the
IR11688 is re-armed so that turn on may be triggered for the next conduction cycle.

Programmable Minimum On Time
The minimum on time is set by an external resistor (RMOT) connected between the MOT pin and ground. The
minimum on time can be calculated based on below equation:
T
MOT = RMOT x 2 x 10-11 + 20ns
where 20ns is the typical internal comparator propagation delay.
RMOT value should remain within the upper and lower limits specified under recommended operating conditions.

MOT protection
Under very light load or zero load conditions, the current in the SR MOSFETs becomes discontinuous and may be
shorter than the MOT time in some cases. If this happens, reverse current will flow from the drain to source at the
end of the MOT since the gate drive has been kept on. This reverse current discharges the converter output
capacitor sending energy back to the transformer and resonating to cause voltage ringing at VDS at switch off.
Such ringing may potentially trigger gate turn on leading to further reverse current and subsequent multiple falsely
triggered erroneous gate pulses as illustrated below in Figure 4:
VDS
IDS

Figure 3: Waveform without MOT protection
The cycle-by-cycle MOT protection function detects reverse current at the end of the MOT period and disables the
following gate output pulse preventing further reverse current. The internal comparator and MOT pulse generator
continue to operate under the protection mode even when the gate drive is disabled. This enables the circuit to
continuously monitor the system load current and automatically revert to normal operating mode once the load
current conduction time has again increased to be longer than the MOT. This protection function reduces standby
power losses and can also prevent voltage spikes caused by false triggering at light load.

Driving Logic Level MOSFET
An external gate clamping circuit is recommended when driving logic level SR MOSFETs. The clamping circuit
keeps the gate voltage below 1V during system power up when the IR11688 is not fully biased in UVLO mode,
especially when Vcc is less than 2V. It is not recommended to drive logic level MOSFETs with the IR11688 without
a safety clamping circuit.
Note the gate regulation feature will be lost when using PNP transistor clamping circuit. Use MOSFET clamping
circuit (figure 7) if regulation function is needed.
