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 ...
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 ...
また、100kHz~2.5MHzの固定スイッチング周波数範囲で同期動作が可能であるため、変換効率またはソリューション・サイズに最適化が可能なほか、外付けのサーミスタ (NTC)によるLEDの過熱フォールドバック機能が、LEDアレイを過熱から保護すると同時に、低下した照明出力を保持することが可能。
屋内の野菜の栽培では高輝度LEDを複数使います。LEDを駆動するには通常、定電流回路(例えば700 mA)を使用するのですが、ワンパッケージになっている便利部品がたくさん売っています。 今私が使用しているのはこちらです。1個200円ちょっと。 定電流 ...
This is a design example report of a 14 W PWM-analog dimmable LED driver employing LinkSwitch™-PH LNK406EG. This design features high efficiency, power factor correction, low component count, and ...
Library uses hardware PWM pins, please be sure that you are providing correct ones. uint8_t outputs[] = { 2, 3}; LEDDriver ledDriver(outputs, 2); void setup() { ledDriver.init(); ledDriver.set(1, ...
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 ...
The PWM channel is defined in the device tree overlay file, but the GPIO that is mapped to this channel is defined in Kconfig. The current implementation is swapping the configured PWM channel with ...
