design to achieve various behaviors. In
chosen to supply the device with two benefits:
●
●
As soon as the device starts switching, it immediately receives some energy from the
auxiliary winding. C5 can be therefore reduced and a small ceramic chip (100 nF) is
sufficient to insure the filtering function. The total start up time from the switch on of
input voltage to output voltage presence is dramatically decreased.
The output current characteristic can be maintained even with very low or zero output
voltage. Since the TSM101 is also supplied in forward mode, it keeps the current
regulation up whatever the output voltage is.The V
