All three boards have now been tested at full current. 30 amps out at 20V, driven by a 12V battery (that dropped below 12V during the test) at just over 60 amps.
Everything seems to be working as hoped for. We will mount them is a metal box and use thermal potting as heat sink on the MOSFETs while the load is high. At 15 amps output, it requires no cooling. A success!
The break-out boards are also very nice. Well made…
Thanks for your help in getting these prototype boards made. We will definitely be back!!!
P.S. What is your real (Chinese) name? I know you use an English name for English customers…
