APPLICATIONS INFORMATION
Primary Winding Feedback
The previous work was developed using a separate wind-
ing for voltage feedback. It is possible to use the primary
winding as the feedback winding as well. This can simplify
the design of the transformer.
When using the primary winding the feedback voltage
will be added to the VIN voltage so:
V
VI
ESR R
N
FLYBK
OUT
DS ON
SP
=

()
where NSP is the transformer effective secondary to
primary winding turns ratio. Use the circuit of Figure 2
to get more accurate output regulation. In this case the
regulation equations becomes:
R
V
VI
ESR R
N

DS ON
SP

where VBE is the base emitter drop of the PNP (approxi-
mately 0.7V).
Likewise the load compensation equation needs to be
changed to use NSP instead of NSF so:
RK

ESR R
RN
