SD690XS - NON-ISOLATED LED LIGHTING DRIVE IC

Description

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.

SD690XS_Datasheet NON-ISOLATED LED LIGHTING DRIVE IC WITH BUILT-IN HIGH-VOLTAGE MOSFET, HIGH PFC AND HIGH CONSTANT CURRENT ACCURACY DESCRIPTION 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 in full range is available as its own PFC control. Boundary Conduction mode is adopted for decreasing switching loss and improving the conversion efficiency.
