I need an LED driver with a Li-Ion battery charger integrated onto the same circuit board.

LED Driver:
Provide power to 4 x 3.0A high power White LED's in series powered by 5 series - wired lithium ion batteries. (Buck Driver)
at least 5 brightness Levels (min - max brightness)
Level selection by means of an isolated momentary switch that will also turn the light on and off.

For the charging part, I need it to charge 5 series Lithium Ion batteries in 3 stages.
The charging input will obviously have a different Vin input from the LED Vin input.

Efficacy of the board should be as high as possible.
The design files should be saved in popular file formats.
