LT3511 - Linear Technology

LT3511 Monolithic High Voltage Isolated Flyback Converter

The LT®3511 is a high voltage monolithic switching regulator specifically designed for the isolated flyback topology. No third winding or opto-isolator is required for regulation as the part senses output voltage directly from the primary-side flyback waveform. The device integrates a 240mA, 150V power switch, high voltage circuitry, and control into a high vo.
