Low Standby-Power Off-line PWM converters
Product：PN8147

1、General Description 
The PN8147 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. PN8147 offers complete protection coverage with
automatic self-recovery feature including Cycle-by-Cycle current limiting (adjustable OCP), and overload protection (OLP), over
temperature protection(OTP), Over oltage Protection (OVP), CS Short-Circuit Protection and soft-start. Hi-mode, Eco-mode, Burst
mode operation and device very low consumption helps to meet the standby energy saving regulations and achieve higher
efficiency. Excellent EMI performance is achieved with frequency modulation. The device consists of the high voltage start-up
circuit. The device provides an advanced platform well suited for the application of .The Six Levels of Energy Efficiency Standards,
The Eur2.0, and The Energy Star.
