Fairchild claims world’s first 1000-Volt integrated power switch
The 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 45 Vac to 460 Vac. The device also includes built-in input over voltage protection and a safe auto-restart mode for all protection conditions.
Fairchild’s power switch claims to be the only solution of its kind that provides Abnormal Over Current Protection (AOCP), which protects the power converter from transformer abnormalities which is important for smart metering applications.
With the world’s highest breakdown voltage, the FSL4110LR is a solution for any designer implementing flyback converters that need to meet three phase input voltage or unstable single phase input voltage requirements.
