Applications Information
TRANSFORMER DESIGN CONSIDERATIONS
Successful application of the LT3511 relies on proper
transformer specification and design. Carefully consider
the following information in addition to the traditional
guidelines associated with high frequency isolated power
supply transformer design.
Linear Technology has worked with several leading mag-
netic component manufacturers to produce pre-designed
flyback transformers for use with the LT3511. Table 1
shows the details of these transformers.
