Fairchild Adds New FOD2741 Error Amplifier

Fairchild Semiconductor International (San Jose, CA) announced the introduction of a new optically isolated error amplifier, the FOD2741, which incorporates an optocoupler, precision reference, and error amplifier into an eight-pin white, dual-inline package. The FOD2741 features a high 5,000 VRMS isolation voltage that makes it suitable for offline power conversion applications.

The FOD2741 provides isolated voltage feedback between the secondary and primary sides of power conversion circuits for control and regulation purposes. The FOD2741 may be used in conjunction with a Fairchild power switch and power management devices to simplify switch-mode power supply and dc/dc converter designs. In addition to a 5,000VRMS isolation voltage, the FOD2741 features a 2.5VREF with 0.5 percent, 1 percent and 2 percent tolerance options; a current transfer ratio of 100 to 200 percent; and a low temperature coefficient of 50ppm/degrees C.

The FOD2741 has UL, CSA, VDE and BSI safety agency certification, and the eight-pin, white, dual-inline package is available in through-hole or surface-mount lead configurations. Both configurations are available in 50-unit tube packaging. Surface-mount devices are also available in tape-and-reel packaging with a 1,000-unit quantity on a 13in (330mm) diameter reel.

Now available, the FOD2741 is priced at $0.30 each in 1,000-piece quantities.
