ANALOG DEVICES LT1737IS#PBF

LT1737 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. Its gate drive capability, coupled with a suitable external MOSFET and other power path components, can deliver load power up to tens of Watts. It has a number of features not found on other isolated flyback controller ICs. By utilizing current mode switching techniques, it provides excellent AC and DC line regulation. Its unique control circuitry can maintain regulation well into discontinuous mode in most applications. Optional load compensation circuitry allows for improved load regulation. It is used in application like isolated flyback switching regulators, medical instruments, instrumentation power supplies etc.
