General Description

☆GreenOperation-compatible The XC9260/XC9261 series is a group of synchronous-rectification type DC/DC converters with a built-in P-channel MOS driver transistor and N-channel MOS switching transistor, designed to allow the use of ceramic capacitors.

Output voltage is internally set in a range from 0.8V to 3.6V (accuracy: ±2.0%) increments of 0.05V.

The device provides a high efficiency, stable power supply with an output current of 1.5A to be configured using only a coil and two capacitors connected externally.

Overview

XC9260/XC9261Series ETR05042-004a HiSAT-COT ® Control, 1.5A Synchronous Step-Down DC/DC Converters.
