Helix Entry Outperforms 'Zero Power' Target in Standby

Helix Semiconductors designed its eMpower line of voltage converters, announced at this year’s IEEE Applied Power Electronics Conference (APEC 2017), to meet zero-power expectations for voltage conversion efficiency. The latest addition to the line, the HS200 DC/DC converter, exceeds the zero-power goal by 10 times, consuming 0.5 mW in standby mode, according to Helix.

The HS200 uses Helix’s patented MuxCapacitor voltage reduction technology to achieve 97 percent efficiency at 2.6 W and greater than 90 percent efficiency at 15 W. The MuxCapacitor scheme uses a three-stage architecture (see diagram). Each stage divides its input voltage in half, allowing three voltages to be supported simultaneously up to a maximum total load of 15 W.
