RT8561D Datasheet | Richtek

® High Voltage 8-CH LED Driver General Description The RT8561Dis a 40V 8-CH LEDdriver capable of delivering 30mA to each channel with 10 LEDs (3.6V per diode), for a total of 80 LEDs per driver. The RT8561D is a currentmode Boost converter that operates at 1MHz, with a wide VIN range from 4.5V to 24V and an on chip current switch 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 RT8561D automatically detects and disconnects any unconnected and/or broken strings during operation from the PWM loop to prevent VOUT from over-voltage. The 1.5% matched LED currents on all...
