In the LED lighting design process, engineers can start the specific LED lighting circuit design after selecting the LED driver solution. This circuit design process is not easy, involves determining specific design requirements (such as voltage, current, and number of LEDs), drawing application schematics, performing design analysis, and determining the final bill of materials (BOM), which requires engineers to spend considerable time. And energy.

If you have an easy-to-use online design simulation tool that allows engineers to sit next to the workbench, you can easily do the above work. As the premier high-performance silicon solution provider for energy-efficient electronic products, ON Semiconductor is working with Transim Technology, a semiconductor industry online design solution provider, to launch an interactive GreenPoint® online design simulation tool for high-profile applications. Energy efficient LED lighting applications.

This article will briefly introduce the main functions of this online design simulation tool, and how engineers can easily use this tool through four main steps: “finding the entrance”, “determining the requirements”, “reviewing the design”, and “fixing the BOM”. LED lighting design, and significantly shorten development time and speed up the product launch process.

Main features and currently supported LED drivers

This GreenPoint® design tool provides an interactive online design and verification environment to help accelerate board design for solid state lighting (SSL) solutions. The GreenPoint® design tool automatically calculates the optimal circuit configuration based on user design requirements such as LED configuration, voltage, current, or switching frequency, selects the appropriate inductor and capacitor values, and displays the final design in an interactive online circuit diagram. This GreenPoint® design tool then uses Transim's proprietary WebSIM® technology to help test the proposed solution. This tool is essentially a virtual test bench that provides a variety of analyses to help engineers effectively and efficiently test the performance of their solutions.

Once the design is validated, the GreenPoint® design tool generates bills of materials (BOM) and comprehensive design reports, including simulation results, schematics, and design data. This GreenPoint® design tool combines ON Semiconductor's e-commerce tools to enable users to select different components of the supplier and produce a bill of materials that meets the requirements. Users can also save design documents in a secure and private workspace for later reference and further modifications.

ON Semiconductor's current online design using GreenPoint® design tools includes the CAT4201 high-efficiency buck LED driver, the NCL30000 power factor correction TRIAC dimmable LED driver, and the NCP1010/1/2/3/4 current mode regulator. NCP1529 Energy-Efficient Buck Converter, NCP3065/6 Multi-Topology Switching Regulator, NCP5030 Buck-Boost Converter, NCP5050 Flash White LED Boost Driver, and NSI45 Series Constant Current Regulators and LED Drivers Device. More semiconductor devices will support this design tool in the future.
