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 ...

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 ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

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 ...

The rear light is of utmost importance for road safety. However, since the space required on the electrical module is limited, several functions must be implemented using just one circuit, for example ...

Austriamicrosystems has introduced the AS1121, a 30V, 40mA, 16-channel LED driver with 12-bit PWM (pulse width modulation), dot correction and diagnostics. It is a 16-channel, constant current-sink ...

Rohm has introduced a linear LED driver for automotive use, following close on the heels of its LED driver for motorcycles. BD18336NUF-M is a 3 x 3 x 1mm constant current driver IC that can deliver ...

Date Announced: 19 May 2009 Hsinchu, Taiwan -- Macroblock launches a new 16-bit PWM LED driver with 8-bit digital dot correction, MBI5040. To provide uniformed LED brightness and accurate LED color ...

MILPITAS, Calif., May 08, 2023 (GLOBE NEWSWIRE) — Lumissil Microsystems, a division of Integrated Silicon Solution, Inc. (ISSI), announces the release of its latest 48-channel LED driver with a ...

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 ...

Macroblock has launched a new 16-bit PWM LED driver, MBI5040, with 8-bit digital dot correction. The new digital dot correction designed in MBI5040 not only unifies the LED brightness and avoids the ...
