Power conversion startup debuts ‘Zero Power’ chipset
The eMpower HS100 is a two-chip set with 95 percent efficiency converting AC mains voltage to 5Vdc, especially at light load, no load or standby operating conditions.
At full loads, the eMpower HS100 enables efficiency of greater than 93 percent. It converts North American 120Vac or Japanese 90Vac mains to 5Vdc at 10W, and European 240Vac mains to 5Vdc at 5W with a full range 85-264Vac input voltage and ±5 percent output voltage regulation.
Helix, formerly Semitrex, has been through a change of management and a rebranding in the last six months. “Our patented technology is letting us forge a path to a future where power grids aren’t incredibly overloaded, rolling blackouts and brownouts are not something we must deal with, and fundamentally unstable power from the grid is a thing of the past,” said Harold Blomquist, president and CEO of Helix Semiconductors.
Applications that will benefit from the chipset include smartphone chargers, smart outlets, IoT gateways, remote sensors, smoke alarms, smart LED lighting and thermostats.
Next-generation products include a 0.18 micron chipset for higher power applications, and a 48V DC-DC device for Power over Ethernet and datacom/telecom applications.
The eMpower HS100 is now in the initial stages of sampling. Production samples will be available in the May-June 2017 time frame, with fully qualified production devices being available in volume starting in September 2017.
