The LED driver automatically adjusts the output voltage to keep the output current constant and therefore the light output constant. This works with a single LED or with a chain of string of LEDs ...
FET constant current sources use JFETs and MOSFETs to deliver a load current, which remains constant despite changes in load resistance or supply voltage. A FET constant current source is a type of ...
The LT3954, a DC/DC converter designed to operate as a constant-current source and constant-voltage regulator with an internal 5A switch, is now available from Linear Technology. The LT3954, a DC/DC ...
Most of us are used to thinking in terms of voltage sources so there is rarely a day goes by that we do not think about voltage source loading or use Thevenin’s theorem. But what about current sources ...
