Hi !
I'm looking for the best way for powering a DC motor with batteries.
The motor is 24V and has a consumption of 100mA to 300mA.
I was thinking in using 6 AA batteries (9V) and boost them to 25V with a DC-DC converter like MC34063.
But calculating the components with this page:
**broken link removed**
I found that from 9 to 25V I have a max Iout of 240mA (Imax supported is 1.5A for MC3403), so the efficiency is:
[(25*0.24)/(9*1.5)] = 44% !!
Am I doing something wrong? I thought that MC3403 was a very efficient DC-DC converter.
Does somebody know a better way for powering this motor?
Thanks !!
Enrique.
