Figure 10— IC Supply derived from Auxiliary
Winding in High-Side Rectification
There is another non-auxiliary winding solution
for the IC supply, which uses an external LDO
circuit from the secondary transformer winding.
See Figure.11 and Figure.12, compared with
using auxiliary winding for IC supply, this solution
has a bit higher power loss which is dissipate on
the LDO circuit especially when the secondary
winding voltage is high.
