XC9301A512MR-G

DC DC Switching Controllers Overview

The XC9301A512MR-G is a Buck-Boost DC-DC switching controller manufactured by Torex Semiconductor Ltd. It functions as a positive output step-up and step-down regulator, capable of handling input voltages that may be higher or lower than the regulated output. The device operates at a fixed switching frequency of 180kHz. Packaged in an SOT-25-5 form factor, this integrated circuit is designed for efficient power management in applications requiring flexible voltage conversion capabilities.
