ADP3110A
THEORY OF OPERATION
pulling the gate down to the voltage at the SW pin. When the
low-side MOSFET, Q2, turns on, the SW pin is pulled to
ground. This allows the bootstrap capacitor to charge up to VCC
again.
The ADP3110A is a dual MOSFET driver optimized for driving
two N-channel MOSFETs in a synchronous buck converter
topology. A single PWM input signal is all that is required to
properly drive the high-side and the low-side MOSFETs. Each
driver is capable of driving a 3 nF load at speeds up to 500 kHz.
A functional block diagram of the ADP3110A is shown in
Figure 1.
The high-side driver is in phase with the PWM input. When the
driver is disabled, the high-side gate is held low.
OVERLAP PROTECTION CIRCUIT
LOW-SIDE DRIVER
The overlap protection circuit prevents both of the main power
switches, Q1 and Q2, from being on at the same time. This
prevents shoot-through currents from flowing through both
power switches and the associated losses that can occur during
their on/off transitions. The overlap protection circuit accom-
plishes this by adaptively controlling the delay from the Q1
turn-off to the Q2 turn-on, and by internally setting the delay
from the Q2 turn-off to the Q1 turn-on.
The low-side driver is designed to drive a ground referenced
N-channel MOSFET. The bias to the low-side driver is
internally connected to the VCC supply and PGND.
When the ADP3110A is enabled, the driver output is 180° out
of phase with the PWM input. When the ADP3110A is
disabled, the low-side gate is held low.
HIGH-SIDE DRIVER
To prevent the overlap of the gate drives during the Q1 turn-off
and the Q2 turn-on, the overlap circuit monitors the voltage at
the SW pin. When the PWM input signal goes low, Q1 begins
to turn off (after propagation delay). Before Q2 can turn on, the
overlap protection circuit makes sure that SW has first gone
high and then waits for the voltage at the SW pin to fall from
The high-side driver is designed to drive a floating N-channel
MOSFET. The bias voltage for the high-side driver is developed
by an external bootstrap supply circuit that is connected
between the BST and SW pins.
The bootstrap circuit comprises Diode D1 and Bootstrap
Capacitor CBST1. CBST2 and RBST are included to reduce the high-
side gate drive voltage and limit the switch node slew rate
(referred to as a Boot-Snap™ circuit, see the Application
Information section for more details). When the ADP3110A is
starting up, the SW pin is at ground; therefore, the bootstrap
capacitor charges up to VCC through D1. When the PWM input
goes high, the high-side driver begins to turn on the high-side
MOSFET, Q1, by pulling charge out of CBST1 and CBST2. As Q1
turns on, the SW pin rises up to VIN and forces the BST pin to
VIN to 1 V. Once the voltage on the SW pin falls to 1 V, Q2
begins turn-on. If the SW pin has not gone high first, the Q2
turn-on is delayed by a fixed 150 ns. By waiting for the voltage
on the SW pin to reach 1 V or for the fixed delay time, the
overlap protection circuit ensures that Q1 is off before Q2 turns
on, regardless of variations in temperature, supply voltage, input
pulse width, gate charge, and drive current. If SW does not go
below 1 V after 190 ns, DRVL turns on. This can occur if the
current flowing in the output inductor is negative and flows
through the high-side MOSFET body diode.
VIN + VC(BST). This holds Q1 on because enough gate-to-source
voltage is provided. To complete the cycle, Q1 is switched off by

APPLICATION INFORMATION
A small signal diode can be used for the bootstrap diode due to
the ample gate drive voltage supplied by VCC. The bootstrap
diode must have a minimum 15 V rating to withstand the
maximum supply voltage. The average forward current can be
estimated by
SUPPLY CAPACITOR SELECTION
For the supply input (VCC) of the ADP3110A, a local bypass
capacitor is recommended to reduce the noise and to supply
some of the peak currents that are drawn. Use a 4.7 μF, low ESR
capacitor. Multilayer ceramic chip (MLCC) capacitors provide
the best combination of low ESR and small size. Keep the
ceramic capacitor as close as possible to the ADP3110A.
(5)
IF(AVG) = QGATE × fMAX
where fMAX is the maximum switching frequency of the
controller.
BOOTSTRAP CIRCUIT
The bootstrap circuit uses a charge storage capacitor (CBST1
)
The peak surge current rating should be calculated by
and a diode, as shown in Figure 1. These components can be
selected after the high-side MOSFET is chosen. The bootstrap
capacitor must have a voltage rating that can handle twice the
maximum supply voltage. A minimum 50 V rating is recom-
mended. The capacitor values are determined using the
following equations:
VCC −VD

MOSFET SELECTION
When interfacing the ADP3110A to external MOSFETs, the
designer should consider ways to make a robust design that
minimizes stresses on both the driver and the MOSFETs. These
stresses include exceeding the short time duration voltage
ratings on the driver pins as well as the external MOSFET.

It is also highly recommended to use the Boot-Snap circuit to
improve the interaction of the driver with the characteristics of
the MOSFETs. If a simple bootstrap arrangement is used, make
sure to include a proper snubber network on the SW node.
where:
QGATE is the total gate charge of the high-side MOSFET at VGATE.
V
GATE is the desired gate drive voltage (usually in the range of
5 V to 10 V, 7 V being typical).
High-Side (Control) MOSFETs
VD is the voltage drop across D1.
The high-side MOSFET is usually selected to be high speed to
minimize switching losses (see the ADP3186 or ADP3188 data
sheets for Flex-Mode controller details). This usually implies a
low gate resistance and low input capacitance/charge device.
Yet, a significant source lead inductance can also exist that
depends mainly on the MOSFET package; it is best to contact
the MOSFET vendor for this information.

VGATE
The ADP3110A DRVH output impedance and the input
resistance of the MOSFETs determine the rate of charge delivery
to the internal capacitance of the gate. This determines the
speed at which the MOSFETs turn on and off. However, because
of potentially large currents flowing in the MOSFETs at the on
and off times (this current is usually larger at turn-off due to
ramping up of the output current in the output inductor), the
source lead inductance generates a significant voltage when the
high-side MOSFETs switch off. This creates a significant drain-
source voltage spike across the internal die of the MOSFETs and
can lead to a catastrophic avalanche. The mechanisms involved
in this avalanche condition are referenced in literature from the
MOSFET suppliers.
For example, an NTD60N02 has a total gate charge of about
12 nC at VGATE = 7 V. Using VCC = 12 V and VD = 1 V, then
CBST1 = 12 nF and CBST2 = 6.8 nF. Good quality ceramic
capacitors should be used.
RBST is used to limit slew rate and minimize ringing at the switch
node. It also provides peak current limiting through D1. An
RBST value of 1.5 Ω to 2.2 Ω is a good choice. The resistor needs
to handle at least 250 mW due to the peak currents that flow
through it.

to go below one sixth of VCC; then, a delay is added. Due to the
Miller capacitance and internal delays of the low-side MOSFET
gate, ensure the Miller-to-input capacitance ratio is low enough,
and the low-side MOSFET internal delays are not so large as to
allow accidental turn on of the low-side MOSFET when the
high-side MOSFET turns on.
The MOSFET vendor should provide a rating for the maximum
voltage slew rate at drain current around which this can be
designed. When this rating is obtained, determine the expected
maximum current in the MOSFET by

where:

MAX is determined for the VR controller that is used with the
driver. This current is divided roughly equally between
MOSFETs if more than one is used (assume a worst-case
mismatch of 30% for design margin).
PC BOARD LAYOUT CONSIDERATIONS
Use the following general guidelines when designing printed
circuit boards:
LOUT is the output inductor value.
•
•
•
•
•
Trace out the high current paths and use short, wide
(>20 mil) traces to make these connections.
Minimize trace inductance between the DRVH and DRVL
outputs and the MOSFET gates.
Connect the PGND pin of the ADP3110A as closely as
possible to the source of the lower MOSFET.
Locate the VCC bypass capacitor as closely as possible to the
VCC and PGND pins.
When producing the design, there is no exact method for
calculating the dV/dt due to the parasitic effects in the external
MOSFETs as well as the PCB. However, it can be measured to
determine if it is safe. If it appears the dV/dt is too fast, an
optional gate resistor can be added between DRVH and the
high-side MOSFETs. This resistor slows down the dV/dt, but it
also increases the switching losses in the high-side MOSFETs.
The ADP3110A is optimally designed with an internal drive
impedance that works with most MOSFETs to switch them
efficiently, yet minimizes dV/dt. However, some high speed
MOSFETs can require this external gate resistor, depending on
the currents being switched in the MOSFET.
Use vias to other layers, when possible, to maximize
thermal conduction away from the IC.
The circuit in Figure 15 shows how four drivers can be
combined with the ADP3181 to form a total power conversion
solution for generating VCC(CORE) for an Intel® CPU that is
VRD 10.x compliant.
Low-Side (Synchronous) MOSFETs
The low-side MOSFETs are usually selected to have a low on
resistance to minimize conduction losses. This usually implies a
large input gate capacitance and gate charge. The first concern is
to ensure the power delivery from the ADP3110A DRVL does
not exceed the thermal rating of the driver (see the ADP3186,
ADP3188, or ADP3189 data sheets for Flex-Mode controller
details).
Figure 14 shows an example of the typical land patterns based
on the guidelines given previously. For more detailed layout
guidelines for a complete CPU voltage regulator subsystem,
refer to the Layout and Component Placement section in the
ADP3181 data sheet.
C
BST1
The next concern for the low-side MOSFETs is to prevent them
from inadvertently being switched on when the high-side
MOSFET turns on. This occurs due to the drain gate (Miller
capacitance, also specified as Crss capacitance) of the MOSFET.
When the drain of the low-side MOSFET is switched to VCC by
the high-side turning on (at a rate dV/dt), the internal gate of
the low-side MOSFET is pulled up by an amount roughly equal
to VCC × (Crss/Ciss). It is important to make sure this does not put
the MOSFET into conduction.
R
C
BST
BST2
D1
Another consideration is the nonoverlap circuitry of the
ADP3110A that attempts to minimize the nonoverlap period.
During the state of the high-side turning off to low-side turning
on, the SW pin and the conditions of SW prior to switching are
monitored to adequately prevent overlap.
C
VCC
Figure 14. External Component Placement Example
However, during the low-side turn-off to high-side turn-on, the
SW pin does not contain information for determining the
proper switching time, so the state of the DRVL pin is monitored
