12Vin -> 3.3Vout
TPSM84209 and ADM7172.
I trimmed the output of the TPSM84209 to about 3.5v as the ADM7172 was just cooking at 1st as the output was nearer 4.5V !
The PCB is way to small for heat dissipation but I could get an idea of how well this would or would not work. I used my new digital dummy load and ramped up the 3.3v load to 1.8A before it just got to hot and cut out.
I think I need 3.3v 1.6A peek and an average of around 450mA so it should would
fine especially if I put this on the main 4 layer Digi board.
there was significant drift on the the 3.3v output under load but just about within range.
Not really convinced of this combo but the footprint / part count is small so I may
give it try on the main board on next revision and experiment with different input / output cap to see if I can get a more consistent voltage output over load / temp range.
Are you sure? yes | no
