XM5084

XM5084 ______________________________________________________________________________________________________ 1.2A Synchronous Step-Down DC/DC Converter GENERAL DESCRIPTION The XM5084 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 circuit smaller. The XM5084 is available in an adjustable output voltage version. The adjustable version has wide output range from 0.6V to VIN. The XM5084 series products are available in a low profile (1mm) tiny SOT23-5 package. FEATURES 1.2A Output Current High...
