As technology continues to evolve, linear solutions are becoming more diverse and widely adopted. However, the elimination of chip capacitors in such systems introduces a range of challenges. One significant issue is that voltage instability can lead to fluctuations in light output, affecting the performance and reliability of LED lighting systems.
Recently, Shenzhen Ming Microelectronics Co., Ltd. (referred to as "Ming Micro Electronics") introduced the SM2096E chip, a breakthrough solution that effectively addresses the problems caused by the absence of chip capacitors. This innovative design ensures stable performance even under varying input voltages, making it ideal for a wide range of applications.
The SM2096E is a dual-channel LED linear constant current control chip that features line voltage compensation and thyristor dimming capabilities. It uses patented constant current and constant power control technology to regulate output current by monitoring the VT port voltage. This ensures consistent light output regardless of input voltage changes. Additionally, the chip includes an over-temperature protection function, automatically reducing output current when the temperature becomes too high, thus enhancing system reliability and longevity.
From a design perspective, the SM2096E is packaged in an ESOP8 format, which simplifies the peripheral circuitry and reduces overall product costs. Its compact and efficient design makes it a preferred choice for manufacturers looking to optimize both performance and cost.
According to reports, the SM2096E supports two main application scenarios: thyristor dimming and non-dimming configurations. In dimming mode, it significantly improves the efficiency of the dimming system, with reported efficiency reaching up to 82%. The chip also offers excellent line regulation (<10%) and supports a 9W/800LM dimming scheme.
In non-dimming applications, the SM2096E not only enhances system efficiency but also achieves a power factor (PF) greater than 0.7, enabling a 9W/800LM non-dimming solution. These features make it suitable for a variety of lighting products, including LED bulbs, downlights, and E14/E27 filament lamps.
Performance comparisons show that the SM2096E outperforms traditional solutions in terms of efficiency, stability, and thermal management. EMI test results further confirm its compliance with industry standards, ensuring reliable operation in real-world environments.
Ming Microelectronics specializes in developing power management, LED lighting, and LED display driver chips. With over 350 intellectual property rights, the company focuses on a technical strategy centered around quality, cost-effectiveness, refinement, and mutual benefit. Its goal is to become a globally recognized brand in the electronics industry.
With its advanced technology and customer-focused approach, the SM2096E has already gained widespread recognition in the market, proving its value in modern LED lighting systems.
