July 29, 2010 -- Supertex, Inc. today introduced the SR10, a capacitor-coupled, switched shunt regulator for direct AC line operation. Its standby power consumption is very low, making it ideal for "always on" standby applications like utility meters, audio/video, or white goods.

The IC operates at high efficiency while requiring no magnetic components or high voltage electrolytic capacitors. Its output can be internally programmed at 6V, 12V or 24V, or can be externally adjusted with a feedback divider from 6V to 28V.

Output current can be scaled via a safety-rated, series coupling capacitor on the AC line. Typical standby power consumption is less than 20mW. The SR10 also uses the safety-rated, high voltage capacitor to meet voltage safety standards for the load. The SR10 solution also meets class B limits for conducted emission.

The SR10 is available in a RoHS-compliant, 8-lead SOIC package (SR10LG-G). Samples are available from stock. Lead-time for production quantities is 4-6 weeks ARO. Pricing for the SR10LG-G is US$0.69 in 1K quantities.
