PN8122
Chipown
Low Standby-Power Off-line PWM converters
General Description
The PN8122 consists of an integrated Pulse Width Modulator (PWM) controller and power MOSFET, specifically designed for a high performance off-line converter with minimal external components. PN8122 offers complete protection coverage with automatic self-recovery feature including Cycle-by-Cycle current limiting (OCP), over voltage protection (OVP), over temperature protection (OTP) and soft-start. Burst mode operation and device very low consumption helps to meet the standby energy saving regulations. Excellent EMI performance is achieved with frequency modulation. The device consists of the high voltage start-up circuit.
