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.

Key Features

  • include programmable output over voltage protection, LED current limit, PWM switch current limit and thermal shutdown. The RT8561A is packaged with a tiny footprint package of WQFN-24L 4x4 packages. Ordering Information RT8561A Package Type QW : WQFN-24L 4x4 (W-Type) Note : Lead Plating System G : Green (Halogen Free and Pb Free) Richtek products are : ` RoHS compliant and compatible with the current require- ments of IPC/JEDEC J-STD-020. ` Suitable for use in SnPb or Pb-free soldering.

® 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 simply programmed with a resistor or a current sink.
