Description
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.
