I have two sets of LED-7-segs.
Each with 4 Digits, all 4 inch tall.
One set CC, the other CA.
Combined they consume some smooth 1.68A / 1.4A according to the data sheets.
That is manifold the current the driver can provide, let alone that the driver is fulled by an Arduino (I'll change that as well).
My question is: What components could I use to supply additional current to the digits?
Basically it seems like I am looking for a certain type of transistor:
Controlled by the driver, it forwards current from a seperate 'unlimited' supply.
At the same time it has to be quite fast, to keep pace with the driver.
I don't want to build this myself, as time matters more than cost,
so out of the box solutions are highly appreciated.
Also I am pretty sure the thing I'm looking for exists, but I can neither find an example part nor the name of such a component.
