产品概述
描述
The EVL4985-350W evaluation board, based on the new L4985 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.
