__________________________________________________________________________________________
2A 1.5MHz Synchronous Step-Down DC/DC Converter
GENERAL DESCRIPTION
The XM5203 synchronous buck converter is a high frequency step-down voltage regulator with current control mode. It can output 2A with excellent line and load regulation. The current is only 130uA at operating and less than 1uA at shutdown. This device is the ideally solution for small space and battery powered consume application, such as cellular phone and Hand-held device.
The XM5203 integrates PWM controller, power switch and compensation network, required only five components to implement a 2A output switching power supply. It has internal fixed 1.5MHz frequency and makes application circuit smaller.
