LT1737
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. ■
