Overview
Over Current Protection IC FP131 General Description FP131 is a current detection and over current protection IC.
It includes a current shunt comparator and shutdown comparator with a precision shunt regulator like FP431.
The rail current detection gain can be adjusted with three external resistors.
The regulator output CSO pin is connected to a shutdown comparator for driving a protection circuit like a photo-coupler to shutdown the converter’s primary side PWM IC when over current occurs.
The voltage shunt regulator has a 1.
25V reference for switching power supply secondary output voltage feedback.
FP131 can be used for OCP and output voltage feedback function with few external parts.
