high amp draw multi led

I have 5 LEDs in one group and groups per unit.

ive scrapped my original design and decided I needed a new approach.

to get into the details ,

I need LOW EMI,
high current
High-Speed Processor
and running 12-24V +/- 10%

ive done some research and i think the
TPS92691-Q1 might be the best option for driving the LEDs, but I'm not sure how to separate into 5 individual Channels to drive a RGBAW type led group.

my range for voltage will be 3.0-3.8v @ 700mA an led so 5 leds in a group strobing individually and never at the same time.

ill post a sketch in a bit
