Maxim’s Automotive LED Controller Eliminates Trade-Off Between Fast Response Time and Low EMI for Exterior Lighting and Improved Safety Applications The MAX20078 synchronous buck, high-brightness LED controller from Maxim Integrated Products, Inc. (NASDAQ: MXIM) is the only product available which provides both fast response time and low electromagnetic interference (EMI) for exterior LED lighting and improved safety applications. Ideal for matrix lighting designs, the LED controller allows designers to achieve high performance, ease of design, and fast time-to-market. In advanced lighting applications such as matrix lighting, LED drivers and controllers have challenges when switching LEDs at high speeds which can cause overshoots and undershoots in current. These applications are not easy to design, as they require numerous LEDs located in a densely-concentrated area and EMI can be especially difficult to eliminate. Automakers spend time, money, and effort trying to achieve low EMI as they experiment with different layouts and filtering methods. The MAX20078 provides ultra-fast response times enabling smoother transient responses. While eliminating the need for external compensation components, it also offers a wide dimming ratio and features both integrated fault protection and monitoring circuitry. The MAX20078 allows for fast LED switching and low EMI so that designers no longer need to sacrifice one for the other. These benefits, along with simplified design and flexible switching frequencies, allow designers to achieve faster time-to-market. Key Advantages High Performance: Ultra-fast response times enable advanced lighting designs Ease of design: Low EMI; no compensation components required; can be programmed using switching frequencies from 100kHz up to 1MHz Fast time-to-market: Integration of components and programmable switching frequency for a simple, flexible design Commentary “We are enabling our customers to create faster, brighter, and more stylish lighting with our latest products,” said Yin Wu, Business Manager, Automotive, Maxim Integrated. “The MAX20078 LED controller is a testament to our continued innovation, as it is the only solution in the market that combines the speed of a hysteretic buck controller with

New family of maXTouch® touchscreen controllers designed for large-screen automotive HMI designs Microchip announces a new family of maXTouch® touchscreen controllers. The MXT1665T-A family of automotive-qualified touchscreen controllers is designed for large-screen automotive Human Machine Interface (HMI) designs. The technology brings multi-touch HMI, such as that experienced on a mobile phone, to car drivers and passengers on screen sizes from 8 to 15 inches. The MXT1665T-A family features Microchip’s adaptive touch technology that uses self-capacitive touch as well as mutual- capacitive touch scanning. This combination provides a multi-touch experience even through thick cover lenses, thick gloves or in the presence of moisture and water. The product family is fully AEC Q100-qualified to address the unique needs of automotive system designs. The family complements the successful MXT641T-A family of products and shares many of the same features developed for the automotive industry. It also supports larger screen sizes above 10 inches in addition to smaller multi- finger pinch separation. The wide range of screen size options within Microchip’s touchscreen controller families enables greater scalability and helps to shorten design time as well as lower system and development costs. The MXT1665T-A family consists of three controllers: the MXT1665T-A supports 1664 touch-node sensors; the MXT1189-A supports 1188 touch-node sensors; and the MXT799T-A with support for 798 touch-node sensors. A designated evaluation kit is available for each of the parts in the MXT1665T-A family. Each kit includes a PCB with maXTouch controller; a touch sensor on a glass/plastic lens;
