产品概述

描述

The STEVAL-LLL004V1 digitally controlled constant current LED driver reference design features a PFC stage and two DC-DC converters designed to work in transition mode (TM) for optimal efficiency.

The LED driver can deliver 75 W output power and implements both analog 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 32-bit STM32F0 microcontroller.

  • 所有功能

    • Wide input voltage range 85 – 265 VAC
    • Transition Mode PFC
    • Two constant current outputs working in transition mode based on different topologies:
      • Buck topology
      • Inverse buck topology
    • Output current: 500 mA ±2.5%
      • Number of LEDs connected at output: 16 – 24 white LEDs (3.3 V each)
    • PFC > 0.97 and THD < 20% at full load with input voltage 85-265 VAC
    • Peak Efficiency at maximum load ≅ 90%
    • Comprehensive safety protections:
      • Open/no-load circuit protection
      • Short-/overload circuit protection
    • Soft start implementation
    • LED dimming range: 0.5% to 100%
      • Analog dimming
      • Digital dimming
    • Dimming control options:
      • Push button
      • 0-10 V input
    • Meets EN55022 Class B
    • WEEE and RoHS compliant
