RT8561B

The RT8561B is a 40V 8-channel LED driver capable of delivering 30mA to each channel with 10 LEDs (3.6V per diode), total of 80 LEDs with one driver. The RT8561B is a current mode boost converter opearated at 1MHz, wide VIN range covers from 4.5V to 24V and the on-chip current switch is rated at 2.5A. The PWM output voltage loop regulates the LED pins to 0.6V with an auto-adjustment circuit allowing voltage mismatches between LED strings. The RT8561B automatically detects and disconnects any unconnected and/or broken strings during operation from PWM loop to prevent VOUT from over voltage.资料下载
