and an optocoupler. The optocoupler is a gallium ars-
enide (GaAs) light emitting diode optically coupled to a
silicon phototransistor. It comes in 3 grades of reference
voltage tolerance = 2%, 1%, and 0.5%.
The Current Transfer Ratio (CTR) ranges from 100% to
200%. It also has an outstanding temperature coefficient
of 50 ppm/°C. It is primarily intended for use as the error
amplifier/reference voltage/optocoupler function in iso-
lated AC to DC power supplies and DC/DC converters.
When using the FOD2741, power supply designers can
reduce the component count and save space in tightly
packaged designs. The tight tolerance reference elimi-
