ISL62381HRTZ

Power Supply Controllers, Monitors Overview

The ISL62381HRTZ is a quad-output system power supply controller designed for notebook applications. It integrates two pulse-width modulation (PWM) controllers featuring Renesas' patented R3 technology, with adjustable output voltages ranging from 0.6V to 5.5V. Additionally, it includes two linear regulators: LDO5 provides a fixed 5V output, while LDO3 offers an adjustable output. The device operates within an input voltage range of 5.5V to 25V and supports a junction temperature range of -40°C to 100°C. It is housed in a 32-VFQFN package with exposed pad.
