General Description

The XC9253R series is a group of synchronous-rectification type DC/DC converters with a built-in 0.6 P-channel driver transistor and 0.7 N-channel switching transistor, designed to allow the use of ceramic capacitors.

The ICs enable a high efficiency, stable power supply with an output current of 500mA to be configured using only a coil and two capacitors connected externally.

Minimum operating voltage is 2.0V~6.0V.
