Multiple auxiliary outputs can easily be derived by winding secondaries on the main output inductor to form a transformer. The secondaries must
be connected so that the energy is delivered to the auxiliary outputs when the Switch Output turns off. During the OFF time, the voltage across
the primary winding is regulated by the feedback loop, yielding a constant Volts/Turn ratio. The number of turns for any given secondary voltage
can be calculated by the following equation:
# TURNS(SEC)
VO(SEC)
VO(PRI)
#TURNS(PRI)
VF(SEC)
VF(PRI)
Note that the 12 V winding is stacked on top of the 5.0 V output. This reduces the number of secondary turns and improves lead regulation. For
best auxiliary regulation, the auxiliary outputs should be less than 33% of the total output power.
