Solutions Search - LT3798 - Isolated No Opto-Coupler Flyback Controller with Active PFC

No-Opto Isolated Flyback Converters

Jun 10th 2016
The no-opto isolated flyback parts from Linear need no opto-coupler or LT1431 shunt regulator for regulation. They sense the isolated output voltage directly from the primary-side waveform. This simplifies the design, allows for a smaller solution size and only requires one component crossing the isolation barrier. The load, ...
