Overview

DATASHEET ISL62391, ISL62392, ISL62391C, ISL62392C High-Efficiency, Triple-Output System Power Supply Controller for Notebook Computers FN6666 Rev 8.00 August 25, 2015 The ISL62391, ISL62392, ISL62391C and ISL62392C controller generate supply voltages for battery-powered systems.

It includes two pulse-width modulation (PWM) controllers, adjustable from 0.6V to 5.5V, and a linear regulator (LDO3) that generates a fixed 3.3V and can deliver up to 100mA.

The ISL62391, ISL62392, ISL62391C and ISL62392C include on-board power-up sequencing, a power-good (PGOOD) output, digital soft-start, and internal soft-stop output discharge that prevents negative voltages on shutdown.
