STMicroelectronics’ EVL400W-EUPL7 evaluation board delivers a ready-to-use 400-Watt power-supply solution that meets today’s toughest eco-design norms. The board leverages innovative features of ST’s L4984D current-mode PFC controller and L6699 resonant half-bridge controller to maximize energy efficiency in multiple operating modes.

Full-load efficiency is over 93% at 230VAC and over 91% at 110VAC, with no-load mains consumption of less than 0.150W, meeting ENERGY STAR® Version 6.1 requirements for computers, European EuP Lot 6 Tier 2 requirements for household and office equipment, and CoC (Code of Conduct) Version 5 Tier 2 for external power supplies. The EVL400W-EUPL7 has also achieved CLEAResult® Plug Load Solutions® 80 PLUS™ certification, rated Platinum at 115V AC and Gold at 230V AC (more info).
