1A Synchronous Step-Down DC/DC Converter
■ General Description
The XM5062S is a current mode synchronous step-down converter with fixed operating. The supply current is only 20uA at operating and less than 1uA at shutdown. This device is the ideally solution for Li-Ion battery powered system applications and small size board applications.
This device has internal switch, no external diode. It has internal fixed 1.5MHz frequency and makes application circuit smaller.
The XM5062S is available in an adjustable output voltage version. It has wide output range from 0.6V to VIN. The XM5062S series products are available in a low profile (1mm) tiny SOT23-5 package.
