Need someone to design a prototype circuit for a SMALL buck/boost microprocessor power supply.
Use PIC12F or Attiny uP
Input voltage of 2V to 7V
Ouput voltage of 3V to [url removed, login to view]
Current control through software from 35mA to 1A
At least 85% efficency
Try to make everything AS SMALL AS POSSIBLE
Written in C
I only require the source code and prototype board, BOM. All application control of the uP will be done on my end.
