The MAX20078 high-brightness LED driver from Maxim Integrated Products, Inc. is the only product available that provides fast response time and low electromagnetic interference (EMI) for outdoor LED lighting and enhanced security applications. In advanced lighting applications, such as matrix lighting, LED drivers and controllers struggle when switching LEDs at high speeds, which can cause overvoltages and undervoltages in the current. These applications are not easy to design, as they require numerous LEDs located in a densely concentrated area, and EMI can be particularly difficult to eliminate.
The MAX20078 delivers 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 integrated fault protection and monitoring circuitry. The MAX20078 enables fast LED switching and low EMI, so designers no longer have to compromise between the two. These benefits, combined with a 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 to 1MHz
• Fast time to market: Component integration and programmable switching frequency for simple and flexible design.
