一.产品概述b70嘉泰姆

CXPR7884 is a current detection and over current protection IC. It includes a current shunt comparator and shutdown comparator with a precision shunt regulator like CXPR7884. 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.b70嘉泰姆
CXPR7884 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 b70嘉泰姆
