Fabless power semiconductor company Helix Semiconductors has announced sampling of the HS200—a DC/DC power IC that converts 48 V to low voltages. The new IC offers greater than 97% efficiency at 2.6 W and greater than 90% efficiency at 15 W. The HS200 is the latest addition to the eMpower family, joining the HS100—an AC/DC chipset that Helix Semiconductors announced earlier this year.
