    ... An effective two-step OVP enables to safely handle overvoltages either occurring at start-up or resulting from load disconnection. The totem-pole output stage, capable of 600 mA source and 800 mA sink current, is suitable for big MOS- FET or IGBT drive which, combined with the other features, makes the device an excellent low-cost solu- tion for EN61000-3-2 compliant SMPS 300W ...

    ... INV will be 2.5V, then: If the output voltage experiences an abrupt change ∆Vo > 0 due to a load drop, the voltage at pin INV will be kept at 2.5V by the local feedback of the error amplifier, a network connected between pins INV and COMP that introduces a long time constant to achieve high PF (this is why ∆ ...

    ... When the load of a PFC pre-regulator is very low, the output voltage tends to stay steadily above the nom- inal value, which cannot be handled by the Dynamic OVP. If this occurs, however, the error amplifier out- put will saturate low; hence, when this is detected, the external power transistor is switched off and the IC put in an idle state (Static OVP) ...

    ... To maximally benefit from the THD optimizer circuit, the high-frequency filter capacitor after the bridge rec- tifier should be minimized, compatibly with EMI filtering needs. A large capacitance, in fact, introduces a conduction dead-angle of the AC input current in itself - even with an ideal energy transfer by the PFC pre- regulator - thus making the action of the optimizer circuit little effective. ...
