As single TP4056 IC rated current is 1A,so I was thinking to connect multiple TP4056 ICs in parallel, such that enough current can be sourced to charge the li-ion battery(400mAh) connected.
Here is the schematic I was going through:
Will this circuit work well or does need any changes? And a schottky diode is being used at the input to maintain the supply voltage level at 5v, I'm guessing that it could be for that reason.
Is that 5.5v Schottky diode necessary? Can I avoid that instead?
