I found it at TME. By the way, has anyone ever seen a P channel depletion MOSFET? |

I would consider the LM10 or more modern LT1635 as a control element. |

The preregulator just needs to deliver "enough, but not too much" :) Working on the layout now, I'll post updates once it works. |

Finished the layout and ordered a few sample PCBs. If (*if*) it works then this will be the first (?) ideal diode module that works with zero output voltage (e.g. a short, or an empty ultracapacitor) 8) Thanks for your help guys! |
