ISL62392HRTZ-T

Power Supply Controllers, Monitors Overview

The ISL62392HRTZ-T is a high-efficiency, triple-output system power supply controller designed for battery-powered systems. It integrates two pulse-width modulation (PWM) controllers with adjustable output voltages ranging from 0.6V to 5.5V and a fixed 3.3V linear regulator (LDO3) capable of delivering up to 100mA. The device operates within a wide input voltage range of 5.5V to 25V and features programmable switching frequencies. It includes on-board power-up sequencing, digital soft-start, internal soft-stop output discharge, and comprehensive protection mechanisms such as overvoltage, undervoltage, and overcurrent protection.
