LED背光驱动

The BCT3221 is a high performance white LED driver. The BCT3221 uses an internal resistor to set the bias current for four LEDs, which are matched to +/-1.5%. The BCT3221's advantages over ballast resistors include much lower bias variation with supply voltage variation, significantly lower drop ·♦ Drive Common Anode or Common Cathode LEDs\n·♦ Low 50mV Dropout at 20mA\n·♦ 20mA full scale current\n·♦♦ One Wire interface for 8-Step Brightness Control\n·♦ 2.7V to 5.5V Supply Voltage Range\n·♦ Thermal Shutdown Protection\n·♦ Low Input Noise and EMI\n·♦ RoHS Compliant QFN-16L Package;
