The BW7381 is a controller for off-line LED converter.
The BW7381 operate with constant off-time, peak current mode control with active power factor correction function.
The controller senses real-time switch current to cycle-by-cycle current limit.
Key Features
Universal Rectified 90VAC to 264VAC Input Voltage Range Built-in Active Power Factor Correction Technique Low THD, meet with IEC-61000-3-2 Class-C High Efficiency.
