This reference design performs a pivotal function in serving to producers rapidly reply to this demand, considerably decreasing R&D cycles, reducing operational prices, and streamlining product improvement.
The Road Mild Good LED Driver Reference Design from Microchip presents a extremely adaptable and cost-effective answer for growing environment friendly LED drivers tailor-made for sensible lighting functions. This design is meant to help intra-luminaire connectivity in compliance with trade requirements, enabling producers to create lighting programs which can be each clever and energy-efficient. With rising world demand for sustainable infrastructure, particularly in municipal environments, the road lighting market is witnessing speedy development.Â
One of the beneficial options of this reference design is its customizability. In contrast to fixed-function, off-the-shelf merchandise, this answer permits producers to tailor the LED driver to satisfy particular mission or municipal tender necessities. This flexibility ensures that merchandise may be tailored for all kinds of use circumstances whereas assembly native laws and requirements, enhancing competitiveness and marketability. Moreover, a whole sensible avenue lighting system demo is out there, which incorporates the LED driver, sensible avenue gentle controller, and help for extensively adopted software program protocols, providing a complete place to begin for product improvement.
From a technical standpoint, the reference design helps an output energy of as much as 100W and operates throughout an enter voltage vary of 190 to 265V AC. It’s compliant with the D4I management technique and achieves a excessive energy issue of 0.99 at 230V AC with 100W output. The system contains each analog (linear) dimming, permitting a variety of LED present management, and PWM digital dimming, which might dim right down to 0.01% brightness with pulse widths as brief as 150 ns.
The design leverages a flyback converter for environment friendly computerized output voltage adjustment and a lift converter that minimizes output ripple, making certain clean LED present. Sturdy safety mechanisms are additionally included, together with undervoltage and overvoltage detection, fault restoration with auto-retry, and overcurrent detection of the load change. Focused utility areas embody avenue lighting, parking space lighting, and industrial lighting. {Hardware} design recordsdata are available, whereas firmware and software program are supplied underneath NDA to certified shoppers and prospects.
The reference design integrates key elements to ship a compact and environment friendly sensible avenue lighting answer. The MCP1792 supplies high-input voltage regulation for automotive-grade reliability, whereas the ATSAMD21E18 microcontroller, with 256KB Flash and 32KB RAM, presents low-power processing for sensible management. The MCP1012 helps environment friendly remoted energy conversion, and the HV96001 allows exact LED modulation with superior PWM and analog dimming. For reliable information storage, the 47L16 combines SRAM velocity with EEPROM non-volatility, making certain dependable, high-endurance reminiscence efficiency.
