微芯的数字LED照明开发工具包让设计者快速地掌握dsPIC33‘GS’系列DSCs的工作性能,以此来开发照明产品。The dsPIC33 ‘GS’ DSC and this reference design allow developers to create a 100% digitally controlled ballast function, while including advanced features such as dimming and color hue control. The dsPIC33 ‘GS’ DSCs can support an entire system implementation for LED lighting products, including power-conversion circuits, such as AC-to-DC and DC-to-DC conversion, along with functions such as Power Factor Correction (PFC), which are necessary for a complete product and lower the overall system cost.Benefits offered by the digital-power techniques in this reference design and the dsPIC33 ‘GS’ series of DSCs include:
Reduced System Cost via higher integration
Higher Efficiency using digital-control techniques
Flexible and reusable designs
Advanced features implemented in software
Example ApplicationsED lighting applications supported by Microchip’s LED Lighting development Kit include dimmable LCD backlighting, signage, LED replacement of fluorescent tubes and incandescent bulbs, architectural lighting, and automotive lighting applications. Automotive lighting products include exterior applications, such as headlights, daytime running lights and signal lights.Key features of Microchip’s Digital LED Lighting Development Kit include:
Color control for RGB LEDs
Supports DMX512 Standard for brightness control
Flexible input voltage support, including both Buck and Boost topologies
Fully dimmable
Full digital control
Fault protection
Fully controlled with a single dsPIC33FJ16GS504 DSC.
