Step Up Battery Voltage Problem


Recommended Posts

Good Day Sirs

I would like to ask for consultation to everyone who will be able to help me with my problem

i made an adjustable stepup voltage dc to dc converter, i was able reach my desired voltage but the problem is, i think it does not supply enough power, so even if i setup the voltage to 6volts once i plug in the device to the circuit the 6volts output drops to like 3+volts? can anyone help me with this? by the way here is the attached pic of the diagram i made using the lm2577

is there by any chance that the circuit be tweaked so it can handle load that big?

No. Your output current is much too high and your input voltage is too low.

maybe i have to replace the stepup regulator?

Select a more powerful stepup regulator that works with your low input voltage.
