Instructions

1. Power Supply Connection:

   • Connect the power supply to the VDD and GND pins. Ensure the supply voltage is within the specified range (2.7V to 5.5V).

2. LED Connections:

   • Connect LEDs to each of the six channels. The maximum current per channel should not exceed 20mA.

3. PWM Dimming:

   • For adjusting brightness, use PWM signals with a frequency between 100Hz and 20kHz. Connect the PWM signal to the appropriate control pin.

4. Temperature Considerations:

   • Operate the device within the temperature range of -40掳C to 85掳C. For storage, ensure temperatures do not exceed -40掳C to 125掳C.

5. Handling Precautions:

   • Avoid exceeding the maximum ratings as it can lead to permanent damage.
   • Ensure proper heat dissipation when operating at higher currents or temperatures.
