FOD2743A - Brand New onsemi Transistor Output Optocouplers
-
Description
The FOD2743A is an Optically Isolated Amplifier that consists of the KA431 precision programmable shunt reference and an optocoupler. It features a gallium arsenide (GaAs) light emitting diode optically coupled to a silicon phototransistor. The device comes in three grades of reference voltage tolerance: 0.5%, 1%, and 2%. With a Current Transfer Ratio (CTR) ranging from 50% to 100% and a temperature coefficient of 50 ppm/°C, it is primarily used as the error amplifier/reference voltage/optocoupler function in isolated AC to DC power supplies and DC/DC converters. By using the FOD2743A, power supply designers can reduce component count and save space in tightly packaged designs. The tight tolerance reference eliminates the need for adjustments in many applications. The device is packaged in an 8-pin DIP white package.
