LT3575 12V-24Vin to Four Output 12V @ 120mA Monolithic Isolated Flyback Converter (No Opto or Third Winding)

Jul 15th 2010
The LT3575 is a monolithic switching regulator specifically designed for the isolated flyback topology. No third winding or opto-isolator is required for regulation. The part senses the isolated output voltage directly from the primary side flyback waveform. A 2.5A, 60V NPN power switch is integrated along with all control logic ...
