Helix Semiconductors manufactures switched-capacitor charge-pump chips. These high-voltage charge pumps can make integral reduction ratios in rectified line voltage. Jeff Sorensen, senior principal applications engineer, showed off Helix chips that can also provide the power for secondary-side feedback optocouplers as well as high-voltage line isolation via the use of X- or Y-rated capacitors.
