RT8511B Description
The RT8511B is an LED driver IC that can support up to 10 WLED in series. It is posed of a current mode boost converter integrated with a 43V/2.2A power switch running at a fixed 500kHz frequency and covering a wide VIN range from 2.7V to 24V. The white LED current is set with an external resistor, and the feedback voltage is regulated to 200mV (typ.).
