Low Standby-Power Off-line PWM converters
General Description
The MD22H 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. MD22H 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.
