Isolated Flyback DC/DC Converters Require No Optocoupler

Isolated Flyback DC/DC Converters Require No Optocoupler
ROHM Semiconductor

The BD7F100HFN-LB is an optocoupler-less isolated flyback converter. An external isolator like optocoupler or a 3rd winding from a transformer which is needed in conventional design of feedback circuits becomes unnecessary in order to obtain a stable output voltage isolated by the transformer. Therefore, the number of parts and space requirements are reduced drastically resulting in a small-sized and high-reliability isolated type power supply solution. The design uses the original Adapted-Type ON-Time Control Technology to control the output voltage and external phase compensation parts are not required.
