General Description

The AP8012H consists of a Pulse Width Modulator (PWM) controller and a power MOSFET, specifically designed for a high

performance off-line converter with minimal external components. AP8012H offers complete protection coverage with

automatic self-recovery feature including Cycle-by-Cycle current limiting (OCP), over temperature protection (OTP),

under-voltage Lockout protection(UVLO)，VDD over-voltage protection(OVP), 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 a high voltage start-up circuit in order to reduce the system set-up time. The

device provides an advanced platform well suited for low standby-power and cost-effective flyback converters.
