The 10W eMpower HS100 chipset enables end to end efficiency of over 90%, says the company, allowing devices to use under 5mW in standby mode. It is developing a 30W device on a smaller geometry and a 48V version.
The capacitive-based voltage reduction allows high efficiency even in light load and no load conditions. Converting AC mains to 5VDC, the HS100 enables more than 90 percent end-to-end efficiency from its full load range of 10W all the way down to 100mA, which represents 5 percent of full load.
The eMpower HS100 is aimed at consumer, business, industrial, automotive, and medical applications in smart phone chargers, smart outlets, IoT gateways, remote sensors, smoke alarms, smart LED lighting, thermostats, consumer goods and white goods user interfaces.
The device is the start of the product roadmap.
"We are currently developing future implementations of our eMpower HS100 in smaller geometries, which will open the door for more applications to experience unprecedented power efficiencies,” said Harold Blomquist, president and CEO of Helix Semiconductors. “Next-generation products include a 0.18 micron chipset for higher power applications, initially targeting 30W, and a 48V DC-DC device for Power over Ethernet, electric/hybrid vehicles and datacom/telecom applications."
