Murata has co-developed the two chip MxC300 to use in 65W transformerless AC-DC designs. Using switching capacitors for power conversion, and by transferring power across a capacitive isolation barrier, the chipset can provide power density improvements of up to 20 times over traditional transformer-based architectures with average efficiencies of greater than 94 percent. It also enables the management of no-load conditions to meet or exceed a Zero Power requirement of under 5mW.
“Helix’s core value proposition of efficiency, maximum power density and scalability very closely aligns with our own design approach. Eventually, these core elements will be extended to all electronics and forever change the way power is delivered,” said said Tatsuo Bizen, director of Murata’s power modules division. “The technology that Helix provides truly sets us apart from competitors, and we see Helix as an important part of our continued technology leadership and innovation.”
Murata has its own capacitor-based technology through pSemi, previously Peregrine Semiconductor. This led to a ‘power supply in package (PSiP)’ module eaerlier this year based on a charge-pump, switched-capacitor architecture that offloads most of the power conversion from the inductor to capacitors in the charge pump. This enables a smaller embedded package.
“When it comes to realizing an energy-efficient future in which not a milliwatt of power is wasted, and a world in which power “bricks” are all but eliminated, it’s all about power density,” said Harold Blomquist, president and CEO of Helix. “Getting the maximum amount of power in the smallest space possible is the key, and Murata’s best-in-class, innovative power products will help achieve this. Partnering with a company as highly respected and influential as Murata will maximize market adoption – and bring us closer to that vision of the future than ever before.”
