Description

The XM5202 synchronous buck converter is a high frequency step-down voltage regulator with current control mode. It can output continuous 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 board level power supply application.This device integrates PWM controller, power switch and compensation network, required only three components to implement a switching power supply. It has internal fixed 1.5MHz frequency and makes application circuit smaller.The XM5202 is available in fixed output voltage version, 1.2V, 1.8V, 3.3V, and is also available in an adjustable output voltage version. The adjustable version has wide output range from 0.6V to VIN. The XM5201 series products are available in a SOP8-PP package.
