A 7.0 W NCP1013- -based Flyback Converter
Featuring Low Standby Power
NCP1013- -65 kHz operating in a 7.0 W converter up to
70C of ambient temperature. We can increase the output
board implementing the diagram in Figure 30 and the
following results were achieved, with either the auxiliary
winding in place or through the Dynamic Self- -Supply:
Vin = 230 Vac, auxiliary winding, Pout = 0, Pin = 60 mW
Vin = 100 Vac, auxiliary winding, Pout = 0, Pin = 42 mW
Vin = 230 Vac, Dynamic Self- -Supply, Pout = 0,
Pin = 300 mW
Vin = 100 Vac, Dynamic Self- -Supply, Pout = 0,
Pin = 130 mW
Pout = 7.0 W, η = 81% @ 230 Vac, with auxiliary winding
Pout = 7.0 W, η = 81.3 @ 100 Vac, with auxiliary winding

power since an auxiliary winding is used, the DSS is
disabled, and thus offering more room for the MOSFET. In
this application, the feedback is made via a TLV431 whose
low bias current (100 mA min) helps to lower the no- -load
standby power.
