This application note shows how to use linear voltage regulators to provide a constant current. Two circuits are presented, one for high-side and another for low-side current sources. The MAX1818 and ...

Operating a stepper motor using a fixed (constant) voltage supply results in poor torque at high speeds. Operating a stepper motor using a fixed (constant) voltage supply results in poor torque at ...

Download this article in PDF format. When you connect the gate to the source of a JFET (junction field-effect transistor), it becomes a two-terminal current source. The current that will flow is ...

The LM334 is not only an adjustable current source, but it is also a rectifier. Right on the front page of the TI data sheet are the words: “Reverse applied voltages of up to 20V will draw only a few ...

Described as the industry's first ac/dc-isolated LED driver modules with constant-current circuits optimized for driving high-intensity LEDs, the BP58xx series integrates all necessary LED-driving ...

SAN DIEGO, USA: ROHM Electronics has introduced the industry’s first AC/DC-isolated LED driver modules utilizing constant-current circuits optimized for driving LEDs. The BP58xx series integrates all ...

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 ...
