MPQ3368-AEC1, joining all 8 channel to driver one LED

Lighting Solutions

We plan to use a MPQ3368-AEC1 to driver and LED backlight with 18 V , 1000 mA.

For this we need to join together all the LED channels in oder to have a total current of 1600 mA (8 * 200 mA).

We already foresee that the phase shift feature has to be disabled (as default). Is there any other configuration we need to pay attention?

The setting of the current should be for the maximum of the individual LED channels or the total of all channels combined?

Bellow is a snippet of the schematic we currently have. Can you see any issues?

Hello Luis,

Paralleling these channels all together is fine. I can see that you followed the following typical application schematic quite well:

I would recommend adding the following placeholders in the case you need to compensate the current sensing.

Other than that, everything else given this schematic looks fine.
