STMicroelectronics EVL4986-350W Evaluation Board

STMicroelectronics EVL4986-350W Evaluation Board provides a reference design for a 350W wide-range input PFC pre-regulator based on the L4986 CCM (Continuous Conduction Mode) Power Factor Controller. The reference design is suitable for all Switch Mode Power Supplies (SMPS) from 150W to several kW and complies with IEC61000-3-2 and JEITA-MITI standards.

The STMicroelectronics EVL4986-350W Evaluation Board features embedded 800V high-voltage start-up circuitry, including an X-capacitor discharger and a patented control method. These features enable a simple design, a minimal component count, and a very low input current distortion (THD) in all operating conditions.

Features

  • 90V to 265VAC input voltage range, 45Hz to 65Hz
  • 400VDC regulated output voltage
  • 350W rated output power
  • 65kHz switching frequency
  • 97.8% peak efficiency
  • EMI according to EN55022 Class-B
  • Total Harmonic Distortion (THD)
    • <6% at full load
    • <10% down to 15% load
  • Mains harmonics meet EN61000-3-2 Class-D and JEITA-MITI Class-D
