TRANSFORMER DESIGN CONSIDERATIONS
Transformer specification and design is perhaps the most
criticalpartofsuccessfullyapplyingtheLT3574.Inaddition
to the usual list of caveats dealing with high frequency
isolated power supply transformer design, the following
information should be carefully considered.
Linear Technology has worked with several leading mag-
netic component manufacturers to produce pre-designed
flybacktransformersforusewiththeLT3574.Table5shows
the details of several of these transformers.
