Fairchild Launches World’s First 1000-Volt Integrated Power Switch

SAN JOSE, CA — Fairchild launches the world’s first 1,000V integrated power switch, offering the industry’s highest breakdown voltage in a single package for designing highly reliable switching mode power supplies for smart meter, appliance and industrial systems. The new FSL4110LR integrated power switch eliminates the need for external components found in competing solutions, enabling power designers to easily meet their time to market and reduce bill of materials.

The FSL4110LR integrates a VDMOS SenseFET (BVDSS=1000V) with built in line compensation for wide input voltage range from 45Vac to 460Vac. It also includes built-in input over voltage protection and a safe auto-restart mode for all protection conditions.

“Fairchild’s new power switch is the only solution of its kind that provides Abnormal Over Current Protection (AOCP), which protects the power converter from transformer abnormalities and is particularly important for smart metering applications,” said Gaurang Shah, Sr. VP, Power Systems Business Group at Fairchild. “With the world’s highest breakdown voltage, the FSL4110LR is an excellent solution for any designer implementing flyback converters that need to meet three phase input voltage or unstable single phase input voltage requirements.”
