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.
SD690XS integrates various protections, such as output open
circuit protection, output short circuit protection, cycle-by-cycle
current limit protection, over temperature protection and VCC
over voltage protection.
The start-up current and operating current are low and highlight APPLICATION
LED can be driven with high efficiency in full range
(85VAC~265VAC).
