A 7.0 W NCP1013--based Flyback Converter
Featuring Low Standby Power
Figure 30 depicts another typical application showing a
NCP1013--65 kHz operating in a 7.0 W converter up to
70 ? C of ambient temperature. We can increase the output

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 m A min) helps to lower the no--load
standby power.

Figure 30. A Typical Converter Delivering 7.0 W from a Universal Mains
Measurements have been taken from a demonstration
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
For a quick evaluation of Figure 30 application example,
the following transformers are available from Coilcraft:
A9619--C, Lp = 3.0 mH, Np:Ns = 1:0.1, 7.0 W
application on universal mains, including auxiliary winding,
NCP1013--65kHz.
A0032--A, Lp = 6.0 mH, Np:Ns = 1:0.055, 10 W
application on European mains, DSS operation only,
NCP1013--65 kHz.
