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 ...
The IS32LT3959 is a single inductor, multi-topology controller with constant on-time for driving a ground referenced high-voltage LED string. This single channel switching LED driver integrates a PWM ...
The LM3463 by Texas Instruments is a six-channel LED driver with dynamic headroom control for high-power applications that accurately drives up to six strings of LEDs. The biggest cost reductions in ...
When designing a handheld device with a colour display using white LEDs for backlighting, is it better to use parallel or series connected LEDs? Both architectures have their own advantages when you ...
Sony has taken the wraps off a new backlight tech for LCD panels known as RGB LED. In really simple terms, it's similar to existing mini-LED backlight tech, such as that offered by the BenQ MOBIUZ ...
Adaptive brightness control has become a common feature in modern smartphones, HDTVs, PDAs, tablets, and computer screens. The goal of this feature is to conserve power as well as to make the display ...
Most engineers are quite familiar with typical low-power-indicator LEDs, whether they be surface-mount or the classical through-hole packages. All that's needed to use them is a voltage source and a ...
Google may add native flashlight brightness controls to Pixel phones in the next quarterly release of Android 16. While the hardware has long supported it, Pixel users currently need to use an app to ...
