RT8561C - High Voltage 8-CH LED Driver

Datasheet Summary

Description

The RT8561C is a 40V 8-CH LED driver capable of delivering 30mA to each channel with 10 LEDs (3.6V per diode), for a total of 80 LEDs with one driver.

The RT8561C is a current mode 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.

Features

  • include programmable output over voltage protection, LED current limit, PWM switch current limit.

RT8561C High Voltage 8-CH LED Driver General Description The RT8561C is a 40V 8-CH LED driver capable of delivering 30mA to each channel with 10 LEDs (3.6V per diode), for a total of 80 LEDs with one driver. The RT8561C is a current mode 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 RT8561C automati cally 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 channels can be simply programmed with a resistor or a current sink.
