An LED-driver reference design for an LED replacement of 100W incandescent bulbs has been introduced by Power Integrations, writes Richard WIlson. An LED-driver reference design for an LED replacement ...

In many consumer applications for lighting the cost of existing technology – namely incandescent light bulbs or fluorescent tubes – is so low that LED lighting’s many advantages simply cannot make up ...

Light-emitting diodes are often used with a voltage source from a power-supply output voltage. The output voltage increases until the current through the LEDs reaches the value of the constant-current ...

The future of LED lighting technology is certainly bright. In spite of fluctuations in the economy and the general lighting industry, LED lighting occupies a significant portion of the overall ...

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 ...

Inspired by printed circuit boards, the building block of all electronics, a Dutch designer has created an LED-based light installation that draws upon the familiar etching pattern inside most devices ...

Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...

Texas Instruments Incorporated has introduced a high-power DC/DC boost LED driver (TPS61500) and high-voltage DC/DC boost converter (TPS61175), and expanded its step-down DC/DC converter series with ...

Texas Instruments has released three new power conversion ICs. They are high-power DC/DC boost LED driver (TPS61500) and high-voltage DC/DC boost converter (TPS61175), and a step-down DC/DC converter ...
