s Overview
The AN8083S is an IC for controlling a DC-DC convert-
er suitable for the switching power supply of various
portable equipments. It can operate with input voltage
1.1V or more.
s Features
Operatable with low voltage input (PVCC>1.1V)
Decreased voltage detection circuit built-in
Short-circuit protection feature built-in
Provided with reset output
Synchronizable with outside clock
Low consumption current in stand-by mode
Output voltage in secondary side; 4.8V+0.3V (Variable
by using external resistance)
