AN8092, AN8092S
Overvoltage Protection Circuit Incorporated Switching Power Supply
Overview
The AN8092 and AN8092S are equipped with various pro-
tection functions such as from overcurrent and overvoltage,
which can raise the reliability of the power supply, realizing the
high-speed control up to 500 kHz.
Features
The PWM control frequency of up to 500 kHz and miniatur-
ization realized.
The power MOS FET of large capacitance directly control-
lable
Built-in overcurrent protection function for two systems of
positive side detection and negative one, and intermittent
operation function for protection when overcurrent condition
proceeds further
ON/OFF function allowing the power supply to be started or
stopped by the external signal, and current control function
required for the secondary side control incorporated
Package : 16-pin DIP for the AN8092, 20-pin SOP for the
AN8092S
Able to be released by the external signal after OVP opera-
tion
