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 :

● Internal integrated high voltage MOSFET

● Low starting current (5μA) and working current (1.5mA)

● Built-in synchronous slope compensation

● Realize No Y-CAP system design under 20W

● Built-in frequency jitter can reduce EMI

● Overcurrent and overvoltage protection

● Undervoltage lockout and automatic restart

● Internal soft start circuit

● Burst Mode (Burst Mode)

● Cycle-by-cycle current limiting mode

Application:

● DVD/DVB/set-top box power supply

● Linear power supply replacement

● Computer/server/liquid crystal TV standby power supply

● White home power supply
