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 ...
Texas Instruments Incorporated introduced a new LED controller with constant power regulation. The LM3447 AC/DC LED driver includes a dimmer detect, phase decoder and adjustable hold current circuits ...
What is the PV-Pushback-Effect? How can solar day lamps (SDLs) take advantage of this effect? Solar day lamps (SDLs) are made by simply connecting an LED array to a solar photovoltaic (PV) panel. SDLs ...
Controlling LEDs is really quite simple. As you know, they need to be current limited which is as easy as applying Ohm’s law to your given set of values. To make things even more even there’s a slew ...
