Looking for 12V@10A dc-dc converter from 14.8V @10A battery
(1/1)
muthukural001:
Hello,
For one of my project, I need to convert 14.8V @10A capacity battery to 12V @ 10A...The 14.8V battery source 's cutoff voltage is 12.8V. So, the dc-dc will be used should give 12V output even when the input is 12.8V.
Do anyone crossed the regulator that do the above?...Please suggest...
Thanks,
Muthu

Unless you need isolation or have some other reason, you may just want to use a low-dropout linear regulator instead of a DC-DC or buck converter. At 14.8 volts your linear regulator will be 81% efficient, at 12.8 volts it will be 93%. That's going to be as good or better than most switching converters.
You could use 5 of these LDO linear regulators in parallel, each with a 0.1R or 0.15R resistor in series on the input side.

If you need isolation or want a switching converter for some reason, they do have this:
