SmartEgg®

Single-Stage Zero Voltage Switching PFC and Regulator

Best for AC/DC 140W - 500W

SmartEgg^® is the EcoVoltas AC/DC architecture for medium-power applications that require Power Factor Correction (PFC).

SmartEgg is perfect for AC/DC power converters that range from 140W to 500W where it achieves high efficiency and high power density with an extremely cost-effective Bill of Materials.

SmartEgg has been designed to offer a single-stage converter able to act both as PFC and isolated regulator, cutting by half the Bill of Materials, increasing power density dramatically and improving efficiency in comparison with traditional boost PFC + LLC resonant converters.

SmartEgg is based on a proprietary magnetic component driven by a GaN half bridge on the primary side.

Key features

Single-stage PFC + isolated regulator for 50% BOM reduction
Forced Zero Voltage Switching (ZVS) under every load condition:
Up to 96% efficiency at full load
Up to 92% efficiency at light load
Weak-coupling transformer (k < 1)
