    The ACPPS turns on when the computer powers the 5V for the USB ports, so most likely as soon as the computer powers on.

    If you disable the USB ports they will not be available to windows to use....

    I have also seen failing hard drives do this. I think it was a circuit failure, not a normal motor/head failure

    Once the HD warmed up to some critical temp, it just completely fails, and the...

    You could use a schottky. they have lower forward voltages. ~.2 compared to ~.7

    Sorry bud, You have a v1 which only has 5V regulated. The 12V output, is just the 12V input switched to that pin when the ACPPS is turned on. Any fluctuations of the cars power system will be present...

    The controller I'm using for the v1 dosen't do buck boost, flyback, or SEPIC, like you'll need to get 15V. But its a TI sync buck. In the v2 i use an LM3488 in a sepic configuration. but that chip...

    My big thing with efficiency is because of heat. I have designed a ~50W power supply with no fan. Without active cooling the PS needs to transfer that heat away by natural means. Unfortunately...

    Bump!

    FYI,
    Parts and PCB's have been ordered to construct 15 units. It will still be a few weeks before they are ready to ship.

    Thank you everyone for your patience.
