一.产品概述
The CXSU63115 is a current mode synchronous step-down converter with fixed operating frequency and integrating PFM mode function. In light load condition,PFM function can increase the system efficiency and enhances the life of system power supply. 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 circuitsmaller.
The CXSU63115 is available in an adjustable output voltage version. The adjustable version has wide output range from 0.6V to VIN. The CXSU63115 series products are available in a low profile (1mm) tiny SOT23-5 package.
