Description

• Parameters: NON-ISOLATED LED LIGHTING DRIVE IC WITH BUILT-IN HIGH-VOLTAGE MOSFET, HIGH PFC AND HIGH CONSTANT CURRENT ACCURACY
• Description: The SDH698XS is designed for non-isolated LED driving with floating Buck topology, built-in HV power MOSFET and depletion mode MOSFET are available. With this topology, 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
• Features: Proprietary constant control method (Patent) High power factor without any peripheral integral capacitor (Patent) Built-in high-voltage power supply Built-in VCC regulator Built-in HV power MOSFET and depletion mode MOSFET Constant current with high accuracy for LED (<±3%) PF>0.9 in full voltage range Boundary-Conduction mode LED short circuit protection LED open circuit protection
• Applications: Amplifier, LED Lighting, Lighting, Power Supply
