XC9301A213MR-G

DC DC Switching Controllers Overview

The XC9301A213MR-G is a Buck-Boost DC/DC controller IC manufactured by Torex Semiconductor Ltd. It operates with an input voltage range of 2V to 10V and features a switching frequency of 300kHz. The device provides a single positive output phase with a maximum duty cycle of 92%. It does not include a synchronous rectifier. The component is housed in a SOT-25-5 package and is designed for step-up and step-down voltage conversion applications.

DC DC Switching Controllers Feature Summary

• Buck-Boost topology for versatile voltage regulation
• Wide input voltage support from 2V to 10V
• Fixed 300kHz switching frequency operation
• Non-synchronous rectifier design

DC DC Switching Controllers Applications

• Battery-powered portable electronics
• Systems requiring variable input voltage regulation
• General-purpose DC-DC conversion circuits

DC DC Switching Controllers Procurement Notes

Verify the specific datasheet version and electrical characteristics directly with Torex Semiconductor Ltd or authorized distributors before integration. Confirm that the SOT-25-5 package dimensions and pinout match your PCB layout requirements. Ensure compliance with RoHS standards and check for any recent product lifecycle updates or obsolescence notices from the manufacturer.

DC DC Switching Controllers Selection Notes

Select this component when a non-synchronous Buck-Boost solution is required for inputs between 2V and 10V. The fixed 300kHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the lack of synchronous rectification if efficiency at high loads is a critical constraint, as this may impact thermal performance in dense designs.

DC DC Switching Controllers Part Context
