XC9508 Datasheet - Torex Semiconductor

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. The.
