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 ...

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 ...

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 ...

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 ...

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

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).

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 ...

Most commercial LED flashlightsuse three AAA or AA batteriesin series that produce 4.5V. The batteriesthen drive four white LEDs that connectin parallel. These LEDs can workat voltages as low as 2.7V ...

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 ...
