Street Light Smart LED Driver Reference Design
The Street Light Smart LED Driver Reference Design is a sophisticated LED Driver system with a maximum output power of 100W and an input voltage range of 190–265V AC. It adheres to the D4i control method and boasts a power factor of 0.99 at 230 VAC with a 100W output. The design features both linear (analog) dimming, which offers a wide range of amplitude control for the LED current, and PWM (digital) dimming, capable of dimming down to 0.01% with a PWM pulse width as short as 150 ns. It employs a flyback converter control that automatically adjusts the output voltage to maintain high system efficiency, and a boost converter that ensures near-zero output voltage ripple for a stable LED current. The system includes fault recovery with an auto-retry delay, undervoltage detection for both VDD voltage and supply voltage (flyback output voltage), overvoltage detection for the LED load voltage (boost output voltage) and overcurrent detection for the load switch current.
