Overview:
OB2353/2354/2355/2358 is used to switch the power supply Built-in high-voltage MOSFET current mode PWM controller series products.
This circuit has low standby power consumption and low starting current. Standby mode , The circuit enters the intermittent working mode, thereby effectively reducing the circuit The standby power consumption.
main feature :
â Internal integrated high voltage MOSFET
â Low starting current (5μA) and working current (1.5mA)
â Built-in synchronous slope compensation
â Realize "No Y-CAP" system design under 20W
â Built-in frequency jitter can reduce EMI
â Overcurrent and overvoltage protection
â Undervoltage lockout and automatic restart
â Internal soft start circuit
â Burst Mode (Burst Mode)
â Cycle-by-cycle current limiting mode
Application:
â DVD/DVB/set-top box power supply
â Linear power supply replacement
â Computer/server/liquid crystal TV standby power supply
â White home power supply
