FP133
Over Current Protection IC With Shunt Regulator
General Description
FP133 is a main rail 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 primary side PWM IC when over current occurs.
The voltage shunt regulator has a 2.5V reference for switching power supply secondary output
voltage feedback.
FP133 can be used for OCP and output voltage feedback function with few external parts. It is
suitable for application in secondary main rail power supply of SPS or isolated fly-back DC-DC
converter.
