Santa Clara, Calif. — National Semiconductor Corp. says it has introduced the industry's first common-anode, current-mode, high-brightness light-emitting diode (LED) driver with pulse-width modulation ...
How a single LED driver can support buck, boost, and buck-boost topologies. Design details for each topology type. How such drivers work in automotive and machine-vision designs. The breadth of LED ...
However LEDs are dimmed – be it by 1 – 10 V analogue voltage, mains phase angle, power-line, digital inputs such as DALI, or a WLAN link, there is in fact only two ways to actually dim the output of a ...
Date Announced: 07 Feb 2012 Sunnyvale, CA – Supertex, Inc. (Nasdaq GS: SUPX) today introduced HV9989, a three channel, boost LED driver integrated circuit (IC) designed to drive LEDs in LCD ...
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, ...
KP1601X is a high efficiency Buck LED power switch designed for LED backlight. It adopts quasi-resonant control mode and integrates accurate zero-crossing detection of inductor current, which can work ...
Infineon has brought out an LED driver IC with a hybrid dimming mode technology for achieving 0.5% of the target current. With its supply voltage range from 8 V DC up to 80 V DC, the driver IC ...
To simplify incandescent-like LED dimming – where colour temperature (CCT) falls with intensity – Dialog Semi has introduced a single chip dual output power converter that needs no microcontroller.
Have you ever looked at your phone and gotten a headache? Sometimes, it just means you've been on it too long and need to take a break. For some folks like me, it's the display itself that's causing ...
