    High Power
    Isolated Flyback Controller
    U FEATURES DESCRIPTIO ■ The LT®1737 is a monolithic switching regulator controller specifically designed for the isolated flyback topology.
    It drives the gate of an external MOSFET and is generally
    powered from a DC supply voltage. Output voltage feedback information may be supplied by a variety of methods
    including a third transformer winding, the primary winding or even direct DC feedback (see Applications Information). Its gate drive capability, coupled with a suitable
    external MOSFET and other power path components, can
    deliver load power up to tens of Watts. ■
