34V@2.8A LED Street Light Reference Design


Design files


This non-isolated Boost Converter delivers a constant current of 2.8A into 10 series white LEDs from a 24V input voltage source. Open LED circuitry protects the converter from possible damage from an overvoltage condition. This converter offers an extremely high effciency of greater than 96% while using low cost components.

  • 24V +/- 10% input voltage
  • Greater than 96% efficiency
  • Low Cost
  • This reference design has been lab tested and is supported with design files and an application note
