Product Overview

STEVAL-LLL004V1 is a 75W digitally controlled constant current LED driver reference design. It features a PFC stage and two DC-DC converters designed to work in transition mode (TM) for optimal efficiency. The LED driver can deliver 75W output power and implements both analogue and digital techniques for flicker free dimming down to 0.5% of the maximum brightness level. The board features high efficiency, a very high power factor above 0.97, and a low THD across wide input voltage and load conditions, thanks to the high performance ST power products and the advanced algorithms running on the 32bit STM32F0 microcontroller.
  • Wide input voltage range 85 to 265VAC
  • Transition mode PFC
  • 2 constant current O/P in transition mode based on different topologies: buck, inverse buck topology
  • Output current of 500mA ±2.5%
  • PFC 0.97 and THD 20% at full load with input voltage 85-265VAC
  • Peak efficiency at maximum load ≅ 90%
  • Comprehensive safety protections: open/no-load circuit and short-/overload circuit protection
  • Soft start implementation
  • LED dimming range: 0.5% to 100% ( analogue dimming and digital dimming)
  • Meets EN55022 Class B
