Single-Phase Pulse-Width Modulation
(PWM) Controller with Integrated
www.dHatiagshhe-eSt4iud.ceomGate Drivers
The ISL8107 is a single phase, non-synchronous buck
controller with an integrated high-side MOSFET driver. The
controller operates from 9V to 75V input voltage range. The
internal 1.192V reference voltage has a tolerance of ±1%
over the industrial temperature range.
The ISL8107 employs voltage-mode control with
feedforward compensation to provide optimal transient
response and a constant loop gain over a wide input voltage
range. The switching frequency can be programmed from
100kHz to 600kHz by external resistor and capacitor. The
switching frequency can be synchronized to an external
clock signal through the SYNC pin.
The ISL8107 features programmable soft-start, hiccup mode
for short circuit protection, and over-temperature protection.
The overcurrent protection is implemented using MOSFET’s
rDS(ON) sensing. This approach simplifies the implementation
without deteriorating the converter efficiency.
