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 ∗ Bulb Lamp (85VAC~265VAC). ∗ T5/T8 LED Lamp FEATURES ∗ ∗ ∗ ∗ ∗ ∗ ∗ ∗ ∗ ∗ Proprietary constant control method (Patent) Built-in 600V MOSFET Constant current with high accuracy for LED (<±3%) PF>0.9 in full voltage range Boundary-Conduction mode LED short circuit protection (Patent) LED open circuit protection VCC over/under voltage protection Over temperature protection Over current protection ∗ Various LED Lighting ORDERING INFORMATION Part No. SD6901STR SD6902STR SD6904STR Package SOP-7-225-1.27 SOP-7-225-1.27 SOP-7-225-1.27 Marking SD6901S ...
