Datasheet	LT3574 Datasheet

The LT®3574 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.

n 3V to 40V Input Voltage Range n 0.65A, 60V Integrated NPN Power Switch n Boundary Mode Operation n No Transformer Third Winding or Opto-Isolator Required for Regulation n Improved Primary-Side Winding Feedback Load Regulation n VOUT Set with Two External Resistors n BIAS Pin for Internal Bias Supply and Power NPN Driver n Programmable Soft-Start n Programmable Power Switch Current Limit n 16-Lead MSOP Package.
