Maxim announced the MAX20078 Synchronous Buck, High Brightness LED Controller, the industry's only component that provides both fast response time and low EMI (EMI) for external LED lighting and improved safety applications. The LED controller can be used for matrix lighting design, providing designers with high-performance, simple design, and can quickly market solutions. The following are the same as the "

In advanced lighting applications such as matrix lighting, LED drivers and controllers may cause upward overshoot and downward overshoot when switching high-speed switching. Such applications are difficult to design because of the need to install large numbers of LEDs in high-density areas, and EMI may be particularly difficult to eliminate. Car manufacturers tend to spend a lot of time, money and effort, according to their test of different layout and filtering methods, efforts to reduce EMI.

The MAX20078 provides ultra-fast response times to support smoother transient reactions without external compensation components, as well as a wide range of dimming ratios, as well as integrated fail-safe and monitoring circuit features. The MAX20078 supports both fast LED switching and low EMI, so designers do not have to worry about this trade-off. The above features combine the simplicity of the design and the flexibility of the switching frequency to help designers bring the product to market quickly.

Main advantage

High performance: fast response time to achieve advanced lighting design

Design simplicity: low EMI; no compensation components; programmable control using switching frequency from 100kHz to the highest 1MHz

Fast time-to-market: component integration and program-controlled switching frequency provide design flexibility and reduce design burden
