Flyback burst mode
Did you know?
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 http://www.electronicrepairguide.com/flyback-transformers.html
