To whom it may concern,
I am an experienced hardware developer of SMPS designs. I am a degree qualified engineer with a BEng(Hons) Electrical and Electronic Engineering and MIET.
The given specification of:
Input 12V (Tx)
Output 5V 3A (Rx)
Will be incredibly challenging and requires significant design effort to achieve.
At present, there are limited vendors offering high power (Tx i/p 12V @>15W) solutions that will meet this (Rx o/p 5V@3A) specification.
Regards
William Holt
