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 ...

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).

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 ...

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 – ...

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

A Simple Over-Voltage Protection Circuit for LED Drivers This boost circuit implements current mode control and senses the LED current via resistor R14. The output voltage is boosted to just over 30V ...

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 ...

Although LED lifetime can reach about 20 years and the power consumption will be less than the incandescent lamp it replaces, the LED bulb's overall cost must also be factored in.
