BD521GOFJ Datasheet (ROHM) - AC/DC controller

BD521GOFJ, AC/DC controller

BD521GOFJ is an AC/DC converter for LED lighting.

This IC can be applied to quasi-resonant typed high-side LED driver application, and the high current precision and low EMI noise can be achieved.

Moreover, owing to the built-in PFC (Power Factor Correction) converter, the harmonic is improved.
