Circuit Protection Requirements All LED drivers need various devices in multiple locations (Fig.2) to protect the circuitry from overvoltage and overcurrent events. Today, there are a few key industry ...

Therefore, each LED driver will be a 350 mA current source designed to work from an input of 45V to 51V over a range of output voltage from 30V to 40V, reflecting the potential variation of the VF of ...

The design always begins with the load and then works its way backward to the source. The problem today is that many people are trying to choose off-the-shelf LED ballasts and then design the LEDs ...

To counter the above described problems, this led dimmer project allows you to do the adjustment of the LED display’s brightness using just a few components. The series resistors are not needed ...

In order to design an effective alternative, Yang’s team needed to fabricate a network of wires that was dense enough to distribute electric current throughout the screen, but also sparse enough to ...

Suppose we want to drive an LED string with 400 mA. Drivers U1 and U2 (MAX16803) are good for automotive use because they have a high input-voltage range, excellent thermal qualities, and the ...

LED dimming circuits are used to differentiate the brightness level through a pulse-width-modulation (PWM) driving technique, which modulates the width of the current pulses applied to the LEDs.

The 555 timer is one of the most versatile integrated circuits available. It can generate PWM signals, tones, and single-shot pulses. You can even put one in a bi-stable mode similar to a flip ...

Diode makes software to design printed circuit boards, which are used in most electronics. The startup raised $11.4 million in Series A funding led by A16z.
