Well...
Its time for an update!!!
Had a hella time with remembering on how to use Altium LOL
Schematic for the LME3463 and drivers are almost laid out.
Have to call the TI tech line to have a quick chat with an engineer to settle my mind as I been at this for about 6 hrs now with no break and I'm about burnt out!
Aiming for 3-5A MAX per channel... so ramping, current limiting and start-up current control are critical to keep heat dissipation to a minimum as well as keeping a constant voltage and constant current to the LED's.
I'm about 80% done now and if everything checks out with the TI boys i will start laying out the prototype boards VERY SOON !!
The boards will be set up in a "UNIVERSAL" mode with jumpers to select between Analog, PWM or Serial control and I'm hopeing to keep them around 2" x 4" and 3" x 5"
Most of the PCB will be SMD ( surface mount) beside the FET's which will be T0220 devices. This way a smaller PCB can be used, but FET's will require a heatsink depending on the draw and dissipation.
