XM5081 - 800mA Synchronous Step-Down DC/DC Converter

Description

The XM5081 is a current mode synchronous step-down converter with fixed operating frequency.

The supply current is only 130uA 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.

Features

  • 1.2A Output Current.
  • High Efficiency up to 96%.
  • 2.5V to 5.5V Input Range.
  • Adjustable Output Voltage from 0.6V to V.

XM5081 ______________________________________________________________________________________________________ 1.2A Synchronous Step-Down DC/DC Converter GENERAL DESCRIPTION The XM5081 is a current mode synchronous step-down converter with fixed operating frequency. The supply current is only 130uA 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. It can reach very ripple with small capacity & inductor. The XM5081 is available in an adjustable output voltage version. The adjustable version has wide output range from 0.6V to VIN.
