ISL9103AIRUFZ-T

Voltage Regulators - DC DC Switching Regulators Overview

The ISL9103AIRUFZ-T is a synchronous buck converter manufactured by Renesas Electronics Corporation. It operates with a fixed switching frequency of 2.4 MHz and supports an input voltage range from 2.7 V to 6.0 V. The device guarantees a maximum output current of 500 mA and maintains 3% output accuracy over temperature and line variations. It features a quiescent supply current of 20 µA in skip mode and less than 1 µA in logic-controlled shutdown. The component utilizes a 6-pin, 1.6 mm x 1.6 mm uTDFN package.
