Hi. I am making an electric lighter which uses 3.7v LiPo battery(600mah), TP4056 battery protection (short circuit, overcurrent(3 Amp)) charging module, switch and 25kV transformer. The problem is that transformer has spikes that are over 3 amps and overcurrent protection gets triggered. I could bypass protection features but transformer works till batteries are discharged way to low(2.3V). Any ideas?

 

How are you switching current to the transformer? It sounds like you need a higher frequency.

Schematic?
