AN8086S
Low Voltage Operation IC for DC-DC Converter
s Overview
The AN8086S is an IC for controlling a DC-DC converter
suitable for the switching power supply of various
portable equipment. It can operate with input voltage
1.1V or more. The AN8086S is based on AN8083S with
the output voltage in the secondary side changed to 3.6V.
s Features
• Operatable with low voltage input (PV_CC>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
