Fairchild Semiconductor introduces optically isolated error amplifier

Sept. 13, 2001
Sept. 13, 2001--Fairchild Semiconductor, at the opening of PowerSystems World 2001, announced the introduction of a its FOD2712 Optically Isolated Error Amplifier.

Fairchild Semiconductor (NYSE: FCS), at the opening of PowerSystems World 2001, announced the introduction of a its FOD2712 Optically Isolated Error Amplifier, which combines an error amplifier, reference voltage, and optocoupler in an 8-pin small outline package for use in isolated ac to dc power supplies and dc to dc converters. This allows power supply designers to reduce the component count and save space in tightly packaged designs.

The optocoupler is a gallium arsenide (GaAs) light-emitting diode optically coupled to a silicon phototransistor, and provides 2,500 VRMS isolation. The reference voltage is 1.24V with a ±1 percent tolerance, the current transfer ratio (CTR) range is 100 to 200 percent, and the operating temperature range is -40 to +85°C. The FOD2712 has CSA and UL safety agency certifications, and VDE and BSI safety agency certifications have been applied for and are pending.

The FOD2712 is available now at $0.35 each in 500 piece quantities
