Introduction
Many
TOPSwitch
flyback power supply applications require
two or more outputs to supply a variety of secondary circuits.
Typical consumer applications of these multiple output
converters include television and related products such as set-
top decoders and video cassette recorders (VCRs). Industrial
applications generally require a number of outputs to supply
analog and digital low voltage circuitry. Motor control
applications often require several separately isolated outputs
to supply half-bridge drivers and control circuitry.
When compared to single output flyback supplies, multiple
output applications demand further design considerations to
