Overview

® RT8561A High Voltage 8-CH LED Driver General Description The RT8561Ais a 40V 8-CH LEDdriver capable of delivering 30mA to each channel with 10 LEDs (3.
6V per diode), total of 80 LEDs with one driver.
The RT8561A is a current mode boost converter operated at 1MHz, wide VIN range covers from 6V 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 RT8561A automatically detects and disconnects any unconnected and/or broken strings during operation from PWM loop to prevent VOUT from over voltage.
The 1.
5% matched LED currents on all channels are si...
