XC9235A21C0R-G

Voltage Regulators - DC DC Switching Regulators Overview

The XC9235A21C0R-G is a synchronous step-down DC/DC converter manufactured by Torex Semiconductor. It operates within an input voltage range of 2 V to 6 V and provides a fixed output voltage of 2.1 V at a maximum output current of 600 mA. The device utilizes a buck topology with a selectable switching frequency of either 1.2 MHz or 3.0 MHz. Quiescent current is specified at 15 uA. It functions reliably across an operating temperature range from -40 °C to +85 °C and is housed in a WLP-5-03-5 package.
