PN8106 - Low Standby-Power Off-Line PWM Converters

PN8106 - Low Standby-Power Off-Line PWM Converters

General Description
The PN8106 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. PN8106 offers complete protection coverage with automatic
self-recovery feature including Cycle-by-Cycle current limiting (OCP), over voltage (OVP) and overload protection (OLP), 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. The device provides an advanced platform well suited for low standby-power and cost-effective flyback
converters.
