XDPL8221

Digital LED driver controller combines a multimode PFC stage with a multimode flyback controller using primary-side regulation. The controller supports universal AC and DC input from 90 V rms to 305 V rms and provides constant-current, constant-voltage, and limited-power output control. UART communication enables parameter configuration and status readout, while PWM dimming supports flicker-free output-current reduction down to 1%. The device integrates a 600 V high-voltage startup cell and provides configurable protections for output, input, bus, VCC, overcurrent, and temperature faults. It is supplied in a PG-DSO-16 package with tape-and-reel packing of 2500 units.
