XC9276 Datasheet (Torex) - Synchronous Step-Down PFM DC/DC Converter

XC9276, Synchronous Step-Down PFM DC/DC Converter

The XC9276 Series is a 150mA step-down synchronous rectification DC/DC converter which has an output voltage switchover function with an ultra-low power consumption circuit and a PFM control.

The efficiency performance at a light load current is dramatically improved by implementing ultra-low power
