Product Summary

The ISL62392 is a High-Efficiency, Triple-Output System Power Supply Controller for Notebook Computers. The applications of the ISL62392 include Notebook and Sub-Notebook Computers, PDAs and Mobile Communication Devices and 3-Cell and 4-Cell Li+ Battery-Powered Devices. 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 ISL62392 includes on-board power-up sequencing, a powergood (PGOOD) output, digital soft-start, and internal soft-stop output discharge that prevents negative voltages on shutdown.
