The MxC 300 is the world’s first chip to use a capacitive isolation (CapIso™) barrier instead of a transformer for an ac-dc power supply, a feat achieved through Helix Semiconductors’ core energy-efficient MuxCapacitor® (MuxCap™) 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.
