By ROHM Semiconductor 78
ROHM Semiconductor's BD7F100 is an optocoupler-less isolated flyback converter. An optocoupler, or the tertiary winding feedback circuit, which was needed to obtain a stable output voltage isolated by a transformer in the conventional application becomes unnecessary; thus, the number of parts is reduced drastically, producing a small-sized and high-reliability application-isolated type power supply.
It uses original adapted-type ON-time control technology to realize high-speed load response making external phase compensation parts unnecessary; therefore, a highly efficient, isolated type power supply application can easily be produced.
