ISL9103AIRUJZ-T

Voltage Regulators - DC DC Switching Regulators Overview

The ISL9103AIRUJZ-T is a synchronous buck converter manufactured by Renesas Electronics Corporation. It operates with a fixed switching frequency of 2.4 MHz and delivers a guaranteed output current of 500 mA. The device accepts an input voltage range from 2.7 V to 6.0 V and provides a fixed 1.8 V output. It features 3% output accuracy over temperature and line conditions, with a quiescent supply current of 20 µA in skip mode and less than 1 µA in shutdown. The component is housed in a 6-pin 1.6 mm x 1.6 mm uTDFN package.
