| FOD2712 Optically Isolated Error FOD2712 Optically Isolated Error Amplifier December 2008 • Optocoupler, precision reference and error amplifier in single package • 1.240V ± 1% reference • CTR 100% to 200% • 2,500V RMS isolation • VDE approval 136616 • BSI approval 8661 and 8662 • UL approval E90700 • CSA approval 1113643 • Power system for workstations • Telecom central office supply • Telecom bricks The FOD2712 Optically Isolated Amplifier consists of the popular RC431A precision programmable shunt reference and an optocoupler. The optocoupler is a gallium arsenide GaAs light emitting diode optically coupled to a silicon phototransistor. The reference voltage tolerance is The current transfer ratio CTR ranges from 100% to It is primarily intended for use as the error amplifier/ reference voltage/optocoupler function in isolated AC to DC power supplies and dc/dc converters. When using the FOD2712, power supply designers can reduce the component count and save space in tightly packaged designs. The tight tolerance reference eliminates the need for adjustments in many applications. The device comes in a compact 8-pin small outline package. Schematic NC 1 C2 E3 8 LED 7 FB 6 COMP 5 GND FOD2712 Optically Isolated Error Pin Number Pin Name Functional Description Not connected Phototransistor Collector Phototransistor Emitter Not connected Ground COMP Error Compensation. This pin is the output of the error Voltage Feedback. This pin is the inverting input to the error Anode LED. This pin is the input to the light emitting diode. *The compensation network must be attached between pins 6 and FAN4803 Control FOD2712 R1 R2 2003 Fairchild Semiconductor Corporation FOD2712 Optically Isolated Error Absolute Maximum Ratings TA = 25°C unless otherwise Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.
