circuits using NCP1052 are presented. These circuits are
designed for cost-saving non-isolated application so that
optocoupler and transformer are saved. The possible input
voltage range is from 20 Vdc to 700 Vdc so that it is suitable
for general AC/DC and DC/DC applications with positive or
negative output voltages. It is noted that the standby ability
of the circuits is not good because of the V
charging current. However, it can be improved by adding an
auxiliary winding to the V
each component in the circuits is explained. By replacing the
NCP1052 with NCP1055, the output current can be
increased. By adding an auxiliary winding, multi-output can
be obtained. A 12 V / 100 mA demo board is presented with
typical 65% efficiency.
