BW7385

BW7385 Non-isolation Buck current control IC with High PFC for LED Lighting Description The BW7385 is a THD and Efficiency adjustable, high accuracy and high power factor constant current PWM controller. This is capable of controlling THD and Efficiency optimization by an external resistor. These functions enable the LED driver to easily meet rule of LED current requirements The IC achieves high power factor and high efficiency by Packing & Order Information BCM mode. The line and load regulation of LED current 3,000/Reel is about ±2.5% because of particular control method. BW7385 also provides gate driving voltage clamping, Pin Configurations (Top View) VCC over voltage protection and system output open/short circuit protection to increase IC performance. Features THD and Efficiency adjustable by RT Pin Low THD <15% (ADJ) Accuracy Constant Current (±2.5%) High power factor (>0.9) Low BOM Cost Applications Boundary Current Mode Control ...
