ISL8105B, +5V or +12V Single-Phase Synchronous Buck Converter PWM Controller

DATASHEET ISL8105B +5V or +12V Single-Phase Synchronous Buck Converter PWM Controller with Integrated MOSFET Gate Drivers, Extended Soft-Start Time FN6447 Rev 2.00 April 15, 2010 The ISL8105B is a simple single-phase PWM controller for a synchronous buck converter.

It operates from +5V or +12V bias supply voltage.

With integrated linear regulator, boot diode, and N-Channel MOSFET gate drivers, the ISL8105B reduces external component count and board space requirements.

These make the IC suitab

ISL8105B Features

* a maximum tolerance of ±1.0% over the commercial temperature range, and ±1.5% over the industrial temperature range. The controller operates with a fixed switching frequency of 300kHz. The ISL8105B features the capability of safe start-up with pre-biased load. It also provides overcurrent protectio
