产品概述

描述

The EVL4986-350W evaluation board, based on the new L4986 continuous conduction mode power factor controller, implements a 350 W wide-range input PFC pre-regulator.

It is suitable for all SMPS from 150 W to several kW and is compliant with IEC61000-3-2 and JEITA-MITI standards.

Thanks to the embedded 800 V high voltage start-up circuitry (that includes also the X-capacitor discharger) and the new patented control method; the main features of this design are the minimal component counts, the simple and easy design and very low input current distortion (THD) in all operating conditions.

Power Good output signal PG_OUT with adjustable comparator input PG_IN for monitoring the PFC output voltage provides design flexibility.

  • 所有功能

    • Universal input voltage range: 90 to 265 Vac, 45 to 65 Hz
    • Regulated output voltage: 400 Vdc
    • Rated output power: 350 W
    • Total Harmonic Distortion (THD): <6% at full load and <10% down to 15% load
    • Power Good output/input signals
    • Switching frequency: 65 kHz
    • Efficiency peak: 97.8 %
    • Mains harmonics: meets EN61000-3-2 Class-D and JEITA-MITI Class-D
    • EMI: according to EN55022 Class-B
