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