高效6通道， 2兆赫， WLED / RGB驱动器

The A8503 is a multi-output WLED/RGB LED driver for medium-size LCD backlighting. It integrates a current-mode boost converter with internal power switch and six current sinks. The boost converter can provide output voltages up to 47 V. The boost converter can drive up to 72 LEDs at 20 mA per LED wi \n• Active current sharing between LED strings for ±0.6% accuracy and matching \n• Drives up to 12 series × 6 parallel = 72 LEDs (Vf = 3.2 V, If = 20 mA) at 5 V \n• Each individual current sink is capable of 32 mA \n• Adjustable overvoltage protection (OVP) \n• 600 kHz to 2 MHz adjustable switch;
