DESCRIPTION
Isolated Flyback Converter
without an Opto-Coupler
The LT3575 is a monolithic switching regulator specic-
ally designed for the isolated yback topology. No third
winding or optoisolator is required for regulation. The
part senses the isolated output voltage directly from the
primary side yback waveform. A 2.5A, 60V NPN power
switch is integrated along with all control logic into a
16-lead TSSOP package.
The LT3575 operates with input supply voltages from
3V to 40V, and can deliver output power up to 14W with
no external power switch.The LT3575 utilizes boundary
mode operation to provide a small magnetic solution with
improved load regulation.
The output voltage is easily set with two external resistors
and the transformer turns ratio. Off the shelf transformers
are available for many applications.
