Description of desired converter/regulator:
1. Low EMI to avoid interference with radio, police two-way comm, cell, etc....
2. Dual conversion required:
1. Low EMI to avoid interference with radio, police two-way comm, cell, etc....
2. Dual conversion required:
a. One conversion circuit (circuit 1) connected to the positive and negative battery terminals but active only when triggered
b. one conversion circuit that gets power when the ingnition circuit is on or accessory on. This circuit gets 12V from the ignition circuit and is used to trigger circuit 1.
c. The triggering is handled in the powered device - triggering is not required in the converter/regulator design- simply a low emi voltage conversion.
d. The powered device measures power at 5.5V at .5A but I want to have more than enough amperage available - if 3-5 A sounds like much more than necessary - I have no problem scaling amperage back.
e. 5V instead of 5.5V to the powered device should not be a problem.
