Maxim Launches LED Driver with Improved EMI Performance
Published2017.02.17 09:22Reduced Harness Wiring and Fault Protection Supporting High-Power Applications
Maxim announced its HB LED driver MAX16833 product.
Global Market Insights projects that the HB LED market size will exceed $22 billion in 2023. Accordingly, the automotive industry's share in the HB LED market is expected to steadily increase.
▲MAX16833 Operating Circuit
LEDs with a lifespan exceeding 50,000 hours offer greater durability compared to other lighting technologies, making them useful for applications such as daytime running lights, and their ability to turn on and off faster than incandescent lamps makes them suitable for brake lighting as well.
The most challenging aspect of HB LED design is addressing EMI issues. Maxim's HB LED driver MAX16833 enhances EMI control performance through frequency dithering for spread spectrum. It is suitable for various automotive lighting applications such as high beam, low beam, signal lighting, daytime running lights, fog lights, and adaptive front-lighting systems (AFLS).
Additionally, it supports high-power applications by reducing harness wiring and providing fault protection. Supporting a maximum input voltage of 65V also reduces system component costs.

Maxim's integrated technology answers IoT design implementation questions.
When encountering the semiconductor company Maxim Integrated, my attention would always fall on the company name 'Integrated.' I would wonder if there was another case where a company embedded what they do best right into their company name. Maxim Integrated was already renowned as a company that excelled at manufacturing Power devices under the company name 'Maxim' alone, and further demonstrated powerful performance by integrating peripheral devices into those power devices. With such a company now emphasizing analog 'integration' right in the company name itself, 'Maxim' and 'Integrated' have come to feel like a single proper noun in the semiconductor industry.
