1.2A Synchronous Step-Down DC/DC Converter
GENERAL DESCRIPTION
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.
able in an adjustable
output voltage version. The adjustable
version has wide output range from 0.6V to
available in a low profile (1mm) tiny
SOT23-5 package.
