OFFLINE PFC FLYBACK SECONDARY CONTROLLED LED STREETLIGHT WITH D4iTM REFERENCE DESIGN
Overview
| Topology | Flyback Converter |
| Input voltage | 190-265 V |
| IC revision | 1 |
Description
The street light market is experiencing significant growth potential as municipalities worldwide are increasingly adopting energy-efficient LED lighting solutions. Utilizing Microchip’s LED Driver reference design allows street light manufacturers to quickly and cost-effectively bring their products to market. Unlike off-the-shelf solutions, Microchip's design offers the flexibility to tailor each driver to meet the specific requirements of various municipal tenders. This customization capability ensures that manufacturers can address the diverse needs of different municipalities, enhancing their competitive edge and ensuring compliance with local regulations and standards.
Features
- Output power: Max 100W
- Input voltage: 190 – 265V AC
- Control method: compliant with D4I
- Power factor 0.99 at 230 VAC, 100W output
- Linear (analog) dimming with wide range of amplitude control of the LED current;
- PWM (digital) dimming, dims down to 0.01% and lower, with PWM pulse width down to 150 ns;
- Flyback converter control with automatic output voltage adjustment for maintaining high system efficiency;
- Boost converter with near-zero output voltage ripple for ripple-free LED current;
- Fault recovery with auto-retry delay;
- Undervoltage detection of VDD voltage and supply voltage (flyback output voltage);
- Overvoltage detection of the LED load voltage (boost output voltage);
- Overcurrent detection of the load switch current
Typical applications
- Smart LED Driver
