How to design LED streetlamp driver circuits In many consumer applications for lighting the cost of existing technology – namely incandescent light bulbs or fluorescent tubes – is so low that LED ...

Analog Circuit Design, Part 5: Integrated 100V controller drives high power LED strings from just about any input ...

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 ...

The Fig. 1 example includes LED loads D1 + D2, D3 + D4, D5 + D6 and a power-supply output voltage, with a constant output current, providing the circuit input voltage (V IN).

It delivers a scalable, efficient, and reliable solution for rear vehicle LED lighting, featuring fault detection, thermal ...

In the industry, I have found that an LED ballast circuit is really more like an AC/DC power supply than like a traditional fluorescent ballast circuit. Today in fluorescent lighting, one need ...

If the LED’s turn-on voltage is lower than the battery voltage, as would be the case with a 6V sealed-lead-acid battery, then you can use a buck converter. Read the associated Circuit Design Idea – ...

The control circuit responds by increasing the PWM on-time to boost the output voltage higher in a failed attempt to increase the LED current. In most instances, the output voltage rapidly rises in an ...

Circuit board design startup Quilter announced on Tuesday it raised $10 million, saying it would use artificial intelligence to reduce the time to design components that power electronics in ...
