RT8511A Description

The RT8511A 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/1.2A power switch running at a fixed 1MHz 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.).
