LED driving device, driving chip and packaging module

The utility model discloses an LED driving device, an LED driving chip and an LED packaging module. The LED driving device comprises a component area which comprises a plurality of functional sub-units forming an LED driving circuit, and different functional sub-units correspond to different sub-circuits forming the LED driving circuit; the channel area comprises a first channel group and a second channel group which are symmetrically distributed on the two sides of the assembly area, the first channel group and the second channel group respectively comprise driving channels with the same number, the assembly area is electrically connected with the channel area, and driving current is provided for the LED lamp beads through the driving channels. By arranging the first channel group and the second channel group on the two sides of the component area, the distances between the component area and the driving channels in the first channel group and the second channel group are the same, so that the output current
