    LT3575
    Isolated Flyback Converter
    without an Opto-Coupler
    FEATURES DESCRIPTION n The LT®3575 is a monolithic switching regulator specifically designed for the isolated flyback topology. No third
    winding or optoisolator is required for regulation. The
    part senses the isolated output voltage directly from the
    primary side flyback waveform. A 2.5A, 60V NPN power
    switch is integrated along with all control logic into a
    16-lead TSSOP package. n 3V to 40V Input Voltage Range
    2.5A, 60V Integrated NPN Power Switch
    Boundary Mode Operation
    No Transformer Third Winding or
    Optoisolator Required for Regulation
    Improved Primary-Side Winding Feedback
    Load Regulation
    VOUT Set with Two External Resistors
    BIAS Pin for Internal Bias Supply and Power
    NPN Driver
    Programmable Soft-Start
    Programmable Power Switch Current Limit
    Thermally Enhanced 16-Lead TSSOP The LT3575 operates with input supply voltages from
    3V to 40V, and can deliver output power up to 14W with
    no external power switch.The LT3575 utilizes boundary ...
