February 18, 2015
The ISL6840, ISL6841, ISL6842, ISL6843, ISL6844,
ISL6845 family of adjustable frequency, low power, pulse
Features
• 1A MOSFET Gate Driver
• 60µA Start-up Current, 100µA Maximum
width modulating (PWM) current mode controllers is
designed for a wide range of power conversion applications
including boost, flyback, and isolated output configurations.
Peak current mode control effectively handles power
transients and provides inherent overcurrent protection.
• 25ns Propagation Delay Current Sense to Output
• Fast Transient Response with Peak Current Mode Control
• Adjustable Switching Frequency to 2MHz
This advanced BiCMOS design is pin compatible with the
industry standard 384x family of controllers and offers
significantly improved performance. Features include low
operating current, 60µA start-up current, adjustable
operating frequency to 2MHz, and high peak current drive
capability with 20ns rise and fall times.
• 20ns Rise and Fall Times with 1nF Output Load
• Trimmed Timing Capacitor Discharge Current for Accurate
Deadtime/Maximum Duty Cycle Control
• High Bandwidth Error Amplifier
• Tight Tolerance Voltage Reference Over Line, Load, and
Temperature

Pin Descriptions
Functional Description
RTCT - This is the oscillator timing control pin. The operational
frequency and maximum duty cycle are set by connecting a
resistor, RT, between VREF and this pin and a timing capacitor,
CT, from this pin to GND. The oscillator produces a sawtooth
waveform with a programmable frequency range up to
Features
The ISL684x current mode PWMs make an ideal choice for
low-cost flyback and forward topology applications. With its
greatly improved performance over industry standard parts, it
is the obvious choice for new designs or existing designs which
require updating.
2.0MHz. The charge time, t , the discharge time, t , the
C
D
switching frequency, f, and the maximum duty cycle, Dmax,
can be calculated from Equations 1, 2, 3 and 4:
Oscillator
The ISL684x family of controllers have a sawtooth oscillator
with a programmable frequency range to 2MHz, which can be
programmed with a resistor from VREF and a capacitor to
GND on the RTCT pin. (Please refer to Figure 4 for the resistor
and capacitance required for a given frequency.)

Soft-Start Operation
D = t f
Soft-start must be implemented externally. One method,
illustrated in Figure 5, clamps the voltage on COMP.
C
Figure 4 may be used as a guideline in selecting the capacitor
and resistor values required for a given frequency.
COMP - COMP is the output of the error amplifier and the input
of the PWM comparator. The control loop frequency
compensation network is connected between the COMP and
FB pins.
VREF
COMP
GND
FB - The output voltage feedback is connected to the inverting
input of the error amplifier through this pin. The non-inverting
input of the error amplifier is internally tied to a reference
voltage.
CS - This is the current sense input to the PWM comparator.
The range of the input signal is nominally 0V to 1.0V and has
an internal offset of 100mV.
FIGURE 5. SOFT-START
Gate Drive
The ISL684x family are capable of sourcing and sinking 1A
peak current. To limit the peak current through the IC, an
optional external resistor may be placed between the
totem-pole output of the IC (OUT pin) and the gate of the
MOSFET. This small series resistor also damps any
oscillations caused by the resonant tank of the parasitic
inductances in the traces of the board and the FET’s input
capacitance.
GND - GND is the power and small signal reference ground for
all functions.
OUT - This is the drive output to the power switching device. It
is a high current output capable of driving the gate of a power
MOSFET with peak currents of 1.0A.
VDD - V
DD
is the power connection for the device. The total
supply current will depend on the load applied to OUT. Total
current is the sum of the operating current and the average

Slope Compensation
output current. Knowing the operating frequency, f, and the
MOSFET gate charge, Qg, the average output current can be
calculated in Equation 5:
For applications where the maximum duty cycle is less than
50%, slope compensation may be used to improve noise
immunity, particularly at lighter loads. The amount of slope
compensation required for noise immunity is determined
empirically, but is generally about 10% of the full scale current
feedback signal. For applications where the duty cycle is
greater than 50%, slope compensation is required to prevent
instability. The minimum amount of slope compensation
required corresponds to 1/2 the inductor downslope. Adding
excessive slope compensation, however, results in a control
loop that behaves more as a voltage mode controller than as a
current mode controller.

OUT
To optimize noise immunity, bypass V
DD
to GND with a
ceramic capacitor as close to the VDD and GND pins as
possible.
VREF - The 5.00V reference voltage output. +1.0/-1.5%
tolerance over line, load and operating temperature. Bypass to
GND with a 0.1µF to 3.3µF capacitor to filter this output as
needed.
Slope compensation may be added to the CS signal shown in
Figure 7.

Fault Conditions
A Fault condition occurs if VREF falls below 4.65V. When a
Fault is detected, OUT is disabled. When VREF exceeds
4.80V, the Fault condition clears, and OUT is enabled.
Ground Plane Requirements
Careful layout is essential for satisfactory operation of the device.
A good ground plane must be employed. A unique section of the
ground plane must be designated for high di/dt currents
associated with the output stage. V
should be bypassed

directly to GND with good high frequency capacitors.
