My latest driver project can be used that way. With just an FET you can ignore all the warnings about needing a custom firmware… just pay attention to the warnings about how hard to build it will be. As I say in the thread, it should not be quite as difficult as it looks - but it’s close. It does use all 0805 sized components, so you can use what you rob from the Nanjg 105c, but since I bypass the protection diode you’ll want to use a different value for R1. Pads are available for either DPAK or LFPAK56 MOSFETs. 17mm DD+7135 — linear regulated driver w/ FET turbo As you can see, there are nothing but 7135’s on the bottom. The entire bottom of that board could just be deleted and replaced with one big BAT+ pad.

For the extra 0805 components (R1, gate resistor, gate pulldown resistor) you can just get them from Chinese eBay vendors 100x for a buck or whatever.

Which LFPAK56 FET are you using?
