XC9261B25CER-G

Voltage Regulators - DC DC Switching Regulators Overview

The XC9261B25CER-G is a synchronous step-down DC/DC converter from the XC9261 series manufactured by Torex Semiconductor. It features HiSAT-COT control and delivers a fixed output voltage of 2.5V at up to 1.5A. The device operates with an input voltage range of 2.7V to 5.5V and utilizes a 1.2MHz switching frequency. Key electrical parameters include a quiescent current of 15uA and a shutdown function. It is housed in a compact 6-UFDFN (USP-6C-6) package with an exposed pad, suitable for surface mount installation across a temperature range of -40°C to +105°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify component authenticity through authorized distributors as this part is officially discontinued. Confirm that the specific suffix matches the required 2.5V fixed output specification. Review the official Product Change Notification (PCN) regarding end-of-life status before finalizing procurement plans. Ensure compatibility with existing PCB footprints designated for the USP-6C-6 package.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component only if the design accommodates its discontinuation status. Verify that the 2.5V fixed output aligns precisely with load requirements, as adjustable variants are not available in this specific suffix configuration. Consider thermal performance within the 6-UFDFN package when designing heat dissipation paths for continuous 1.5A loads.
