SD692XS_Datasheet
NON-ISOLATED LED LIGHTING DRIVE IC WITH BUILT-IN HIGH-VOLTAGE MOSFET, HIGH PFC AND HIGH CONSTANT CURRENT ACCURACY
DESCRIPTION
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 in full range is available as its own PFC control. Boundary
Conduction mode is adopted for decreasing switching loss and improving the conversion efficiency.
