ISL62383CHRTZ

Power Supply Controllers, Monitors Overview

The ISL62383CHRTZ is a high-efficiency power supply controller designed for notebook computer systems. It integrates two pulse-width modulation (PWM) controllers and two linear regulators (LDO5 and LDO3). The PWM outputs are adjustable from 0.6V to 5.5V, providing ±1% output voltage accuracy across an operating temperature range of -10°C to +100°C. The device utilizes High Performance R3 Technology to ensure fast transient response. It is housed in a 28-TQFN (4x4) package and features a supply current of 150µA.
