Hi
I'm currently designing a Boost regulator to convert 12V to 14V. I plan to
use the LM2587 from NS. This reg needs a coil but I can find nowhere the
influence of this coil.
Can anybody help me to choose this coil (specially the value). I need 5A
output capability.

Input : 12V/7Ah (Pb Accumulator), Output 13.8V /50W
and next 12V/4Ah (NiCd Accumulators), output 13.8V/50W

Thanks
