I got these TP4056 modules from an AliExpress vendor and fail to understand how the protection circuit works or if it’s just typical Ali shovelware. It could be my limited understanding of electronics....
Since MOSFETs have a gate capacitance you’d want to limit the inrush of current from the output of a microcontroller to prevent it from getting damaged prematurely. That’s what gate resistors are usually good for....
Does anyone recognise these power supplies? They’re cheap AliExpress led drivers and I want to change its output voltage to around 22V from 12V. I’ve read that the way to do this is to adjust the REF voltage on the IC that controls it. It’s a KA3845 but I don’t understand where that reference voltage is regulated. One...
