XC9508 Datasheet (Torex Semiconductor) - Synchronous Step-Down DC/DC Converter

XC9508, Synchronous Step-Down DC/DC Converter

The XC9508 series consists of a step-down DC/DC converter and a high-speed LDO regulator connected in series with the DC/DC converter's output.

A voltage detector is also built-in.

A highly efficient, low noise output is possible since the regulator is stepped-down further from the DC/DC output.
