The LED backlights in automotive heads-up displays, infotainment systems, and dashboard lighting must be bright enough to compete with direct sunlight streaming into a car during the day, yet capable ...

The FL663 is a highly integrated third-generation Primary-Side-Regulation (PSR) PWM controller that aims to enhance the performance of LED illumination. Using TRUECURRENT® technology, the device ...

LED-driver circuits can be dimmed by applying a variable duty cycle (pulse-width modulation, or PWM) to the LED. PWM exploits LED behavior: At higher current levels, the LED’s light output is higher ...

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 ...

Family of MCU-less matrix LED drivers with 16-bit PWM dimming designed to ISO 26262 process for ASIL-B applications ...

A Mirror surrounded by a string of brightly lit lamps is something you usually get to see in a Movie Star’s dressing room. [pickandplace] was inspired by the Movies, and a dark bathroom, to come up ...

Pulse Width Modulation is definitely the preferred method of dimming an LED with a microcontroller, but we were interested in hearing about a different method called Binary Code Modulation. BCM does ...

Many of today’s portable electronics require backlight LED-driver solutions with the following features: direct control of current, high efficiency, PWM dimming, overvoltage protection, load ...

Lots of modern phones use pulse width modulation, or PWM, to manage brightness. But what is PWM, why is it harmful, and what ...

Yet the S26 series remains at a low 480Hz PWM rate, as confirmed by company representatives. It could be worse; the standard Pixel 10 runs at 240Hz. Samsung’s dimming frequency is also in line with ...
