XYSemi XM5232

Description

The XM5232 synchronous buck converter is a high frequency step-down voltage regulator with current control mode. It can output 2.5A with excellent line and load regulation. The current is only 20uA 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 XM5232 integrates PWM controller, power switch and compensation network, required only five components to implement a 2.5A output switching power supply. It has internal fixed 1.5MHz frequency and makes application circuit smaller.The XM5232 is available in an adjustable output voltage version. The adjustable version has wide output range from 0.6V to VIN. The XM5232 series products are available in a DFN3X3-10L package.
