Part Number: DP104C
Function: Switch Control IC, Monitor Power Management IC Chip
Package : ZIP 5 Pin
Manufacturer : Fairchild Semiconductor
The DP104C is specially designed for an off-line SMPS with minimal external components.
The device consist of high voltage power SenseFET and current mode PWM controller IC.
PWM controller features integrated fixed oscillator, under voltage lock out, leading edge blanking, optimized gate turn-on/turn-off driver, thermal shut down protection, over voltage
protection, temperature compensated precision current sources for loop compensation and fault protection circuit.
