SD6921STR, SD6921ASTR Datasheet (Silan Microelectronics)

SD6921STR, SD6921ASTR, NON-ISOLATED LED LIGHTING DRIVE IC

SD692XS is designed for non-isolated LED driving with floating Buck structure and built-in 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
