SD6902S, SD690XS Datasheet (SILAN MICROELECTRONICS) - NON-ISOLATED LED LIGHTING DRIVE IC

SD6902S, SD690XS, NON-ISOLATED LED LIGHTING DRIVE IC

SD690XS is designed for non-isolated LED driving with floating Buck structure and built-in 600V MOSFET.

With this structure, inductor current is sensed and closed-loop is formed with the internal error amplifier for high constant current accuracy and high input/output regulation rate.

Also, high PF
