I plan on buying a VMA402 step up converter but I’m not sure if it will suit my needs, and the datasheet doesn’t helps me enough.
I need to power a LM358N Op amp.
So I plan on using a 9V battery on the input of the step up converter and tune it (using the knob) to output 48V.
I have 3 questions regarding this module :
- I don’t know if the step up can really output 48V from 9V (by reading the datasheet I’d say yes, but I feel I’m missing something because its seems like a huge voltage conversion)
- How much intput current does it require ? The datasheet says 2 different values (2A - 3A which seems really high for a module designed to step up the voltage of a MCU)
- How would you advise me to power this step up converter ? (battery, powerbank, else ? (I need something relatively small and portable))
Thanks in advance for your help, let me know if you need further details,
