LT3512 Monolithic High Voltage Isolated Flyback Converter

The LT3512 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 420mA, 150V power.
