4A 1MHz Synchronous Step-Down DC/DC Converter

■ General Description
The XM6501 synchronous buck converter is a high frequency step-down voltage regulator with current control mode. It can output 4A with excellent line and load regulation. The current is only 100uA 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 、 SSD device and Hand-held device. 

The XM6501 integrates PWM controller, power switch and compensation network, required only few components to implement a 4A output switching power supply. It has internal fixed 1MHz frequency and makes application circuit smaller. The XM6501 is available in an adjustable output voltage version. The adjustable version has wide output range from 0.6V to VIN. The XM6501 series products are available in a DFN3X3-10L package.
