I need to power two devices at the same time using one only battery,what's the solution ? These devices are :
a) VGA board that wants from 8.5 to 12V
b) the Beagle Board XM that wants 5V
What I'm looking for is a 12V / 5A Switching Power Adapter to use with the battery,not from the AC-DC. The battery with which I want to do the operation is the Tekkeon MP3450i R2. Please kindly note that with this battery you can configure the voltages choosing from 5V to 19V.
