The LT®3573 is a monolithic switching regulator specifi -cally designed for the isolated fl yback topology. No thirdwinding or optoisolator is required for regulaTIon. Thepart senses the isolated output voltage directly from theprimary side fl yback waveform. A 1.25A, 60V NPN powerswitch is integrated along with all control logic into a 16-lead MSOP package.The LT3573 operates with input supply voltages from3V to 40V, and can deliver output power up to 7W withno external power devices.The LT3573 uTIlizes boundarymode operaTIon to provide a small magneTIc solution withimproved load regulation.
