LT3573 9V-30Vin to ±5Vout @ 350mA Monolithic Isolated Flyback Converter (No Opto or Third Winding)

Oct 29th 2008
The LT3573 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 1.25A, 60V NPN power switch is integrated along with all control ...
