560V Input, No-Opto Isolated Flyback Converter

George Qian - Senior Applications Engineer Jan 19th 2017
Design Note 559: Introduction In traditional isolated high voltage flyback converters, tight regulation is achieved using opto-couplers to transfer regulation information from the secondaryside reference circuitry to the primary side. The problem is that opto-couplers add significant complexity to isolated designs: there is ...

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, ...
