International Rectifier’s IRS29831 LEDrivIR integrates an LED driver controller and a 700-V MOSFET optimized for single-stage flyback and buck-boost topologies used in LED drivers, including LED bulb ...
EE and firmware developer [Enrico] had played with LEDs as a kid, burning out his fair share of them by applying too much current. With the benefit of his firmware chops, he set about creating a board ...
This is the circuit diagram of bipolar LED Driver using microcontroller. Here we use an LED which has a forward voltage drop of 2.2V and hence can be biased using a 5V supply. This Bipolar LED Driver ...
Nearly all lighting applications today use LEDs. In a relatively short amount of time, they have become established as the preferred choice of illumination. However, in most applications, an LED can’t ...
CAMPBELL, Calif.--(BUSINESS WIRE)--iWatt Inc., a leading provider of digital-centric power management integrated circuits (ICs), today announced its latest LED driver for LCD TV backlighting. The new ...
PLANO, Texas--(BUSINESS WIRE)-- Diodes Incorporated (DIOD) today announces the expansion of its automotive-compliant* LED driver portfolio by introducing the AL8866Q. This DC-switching LED ...
In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is ...
KIRCHHEIM, Germany--(BUSINESS WIRE)--Dialog Semiconductor plc (FWB: DLG), a provider of highly integrated power management, audio, AC/DC and short-range wireless technologies, today debuted the iW7025 ...
Lumissil Microsystems has introduce a speciallist RISC-V microcontroller for touch-controlled LED-based user interfaces, with optional sound feedback. There are two versions: IS31CS9310 for industrial ...
Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...
The quest for energy efficiency has led manufacturers to investigate ways of dimming all kinds of lighting technologies, including those that usually can’t be dimmed. Consider, for example, ...
