Need help with high current step up DC
I need to design external battery for my flash.
I have checked it works with 4-6v DC with ~6a current to charge the capacitor in 2-3 second.
I have 18650 battery planning to use in 1S configuration. And i need to boost the voltage from 3.7v to ~5-6v .
MT3608 boost modules can provide only 1-2amp max
XL6009 boost modues work with >3.5v so it wouldn't work.
XL4015 step down modules is also not working .. short circuit protection getting triggered.
Is there any modules which can boost to ~5-6v from those 18650 battery and can provide peak current more than >5A for a short period of time.
Or any way to step down from 2S battery pack to ~5-6V with peak current >5A.
Any suggestions would be helpful.
