600mA 4MHz Synchronous Step-Down DC/DC Converter
GENERAL DESCRIPTION
The XF45061 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 4MHz
frequency and makes application circuit
smaller.
The XF45061 is available in an adjustable
output voltage version. The adjustable
version has wide output range from 0.6V to
VIN. The XF45061 is available in a low
profile (1mm) tiny SOT23-5 package.
