Datasheet
General Description
The PN8137 consists of an integrated Pulse Width Modulator (PWM) controller and power MOSFET, specifically designed fora high performance off-line converter with minimal external components. PN8137 offers complete protection coverage withautomatic self-recovery feature including Cycle-by-Cycle current limiting (adjustable OCP), and overload protection (OLP),over temperature protection (OTP) and soft-start. Hi-mode, Eco-mode, Burst mode operation and device very low consumptionhelps to meet the standby energy saving regulations and achieve higher efficiency. Excellent EMI performance is achieved withfrequency modulation. The device consists of the high voltage start-up circuit. The device provides an advanced platform wellsuited for low standby-power and cost-effective fly back converters.
