Description

• Parameters: NON-ISOLATED LED LIGHTING DRIVE IC WITH BUILT-IN HIGH-VOLTAGE MOSFET, HIGH PFC AND HIGH CONSTANT CURRENT ACCURACY
• Description: SDH7901SG is designed for non-isolated LED driving with built-in high voltage power MOSFET, high voltage JFET and freewheel diode。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 due to its own PFC control. Boundary Conduction mode is adopted for decreasing switching loss and improving the conversion efficiency. SDH7901SG ca
