WebIt is well-known that many of the power loss sources in a lightly loaded flyback waste energy proportionally to the switching frequency, hence this should be reduced as much as possible. On the other hand, it is equally well-known that a low switching frequency leads to bigger and heavier magnetics and makes filtering more troublesome. WebIt provides a circuit for start-up directly from the rectified mains voltage without any external bleeder circuits. The Burst mode frequency of 1750 Hz enables no-load power consumption below < 53 mW at high mains input.

Webimpacts on OLP, standby power, burst mode point, etc. If too large, it may cause high OLP resulting in system damage, and high burst-mode point resulting in low efficiency under light load, and also high standby power. So the selecting of the sampling resistor should be a trade-off among them. Start-up resistor RST (R4, R5 in Figure 1) and VCC
