Application figures:

Every output channel can drive a maximum load of 15W.

So one should take care when designing the load configuration.

The load per channel can easily be calculated by adding the power consumption of each led connected to the specific channel.

To calculate the power of each led, one should take the forward voltage drop of the LED used and multiply this by the current going through it.

The forward voltage drop (VF) can be found in the data sheet of the LED in question. Please note that VF is always mentioned for a specific current through the LED.

Example 1, picture to the right: every channel has a load of: ( 3,42V * 0,35A) * 8 = 9,58W

Example 2, picture in lower right corner: Ch1, red leds: (2,95V * 0,35A) * 12 = 12,39W Ch2, green leds: (3,42V * 0,35A) * 12 = 14,36W Ch3, blue leds: (3,42V * 0,35A) * 12 = 14,36W








350 driving 24 Luxeon I LEDs (White),
8 in series per channel, total power = 28,7W
