GREEN ISLAND, N.Y. & DÜSSELDORF, Germany & NEW YORK--(BUSINESS WIRE)--Asahi Kasei, a diversified Japanese multinational company, and subsidiary Crystal IS have demonstrated their next-generation ...
Light emitting diodes (LEDs) are low-voltage light sources that require a constant DC voltage or current to operate optimally. Because they operate on a low-voltage DC power supply, they easily adapt ...
Driving tricolor RGB LEDs for enhanced LCD backlighting, the NCP5623 triple-output LED driver has an I 2 C interface and built-in gradual dimming. The device suits portable-system applications, ...
The cult-loved beauty tech brand now has gadgets for nearly every skin—and hair—goal. Every one of the brand’s LED devices is FDA-cleared and CE certified for at-home use. (CE certification is ...
A buck-boost controller IC with four external switching MOSFETs can operate from input voltages above, below, or equal to the output voltage, enabling them to regulate the light output for a string of ...
Figure 284.1 shows a complete LED driver solution. The LT3799 senses the output current from the primary side switch current waveform. Where I PK is the peak switch current, N is the primary to ...
Most small-size color LCD displays today use white LEDs for backlighting. These systems usually involve handheld devices with an LED drive circuit powered by a battery whose output voltage varies over ...
