devonsc said:Would like to ask a few questions regarding the DC/DC converter which i plan to use. I'll be using using the Sun's energy to generate an output of 8-10V, where i will boost the output to a 12V DC level through a DC/DC converter before using for charging purposes. The battery that i will be charging is a 12V DC motorbike battery. Ermm, I do not know the specifications for this battery at this moment but normally, whats the current that will be produced if im using the 12V DC motorbike battery? I was thinking that I can implement the MAX642 IC (switching regulator) in the DC/DC converter circuit to boost the voltage. How do I find out if the respective circuitry to boost my voltage level of 8-10V to a level of 12V DC is suitable to be used to charge the 12V DC battery?
devonsc said:Thanks a lot Nigel, I'll get and study the specification sheet as soon as possible.
Erm, you sound mad, hope I'm not annoying. Real sorry if I am. Thanks again..
makan said:Hey ppl, once again thanx for givin me ur replies...
about the current needed it would be about 0.5mA...
