The LT®3573 is a monolithic switching regulator specifi -
cally designed for the isolated fl yback topology. No third
winding or optoisolator is required for regulation. The
part senses the isolated output voltage directly from the
primary side fl yback waveform. A 1.25A, 60V NPN power
switch is integrated along with all control logic into a 16-
lead MSOP package.
The LT3573 operates with input supply voltages from
3V to 40V, and can deliver output power up to 7W with
no external power devices.The LT3573 utilizes boundary
mode operation to provide a small magnetic solution with
improved load regulation.
