PN8112
Chipown
Current Mode PWM Controller
General Description
The PN8112 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. PN8112 offers complete protection coverage with automatic self-recovery feature including Cycle-by-Cycle current limiting (OCP), 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.
