Helix Semiconductors announced sampling of its MxC® 300 AC-DC power ICs. The MxC 300 is a two-chip solution that offers the highest power density in the industry – up to 10x higher than transformer-based solutions – for 65W AC-DC power supply products.
It is the world’s first chip to use a capacitive isolation (CapIsoTM) barrier instead of a transformer for an AC-DC power supply, a feat achieved through Helix Semiconductors’ core energy-efficient MuxCapacitor® (MuxCapTM) technology. Helix’s CapIso technology eliminates the isolation transformer traditionally used in AC-DC power supplies, providing isolation with capacitors, which meet the UL and IEC standards for safety.
As a result, the chipset enables the replacement of traditional magnetic-windings-based transformers, which are used for isolation and voltage reduction, while providing average power efficiencies of greater than 95 percent. The resulting increase in power density can be significant since the transformer is typically the largest component in the power supply module.
“Energy management has become one of the most important issues of our time, and companies are actively seeking solutions that offer higher power density, greater efficiency and smaller form factors,” noted Harold A. Blomquist, president and CEO of Helix Semiconductors.
