| ====== EVALUATING THE ADUM3190S iCOUPLER ADuM3190s ISOLATED ERROR AMPLIFIER ====== | ====== EVALUATING THE ADUM3190S iCOUPLER ISOLATED ERROR AMPLIFIER ====== |
| ===== Preface ===== | ===== Preface ===== |
| The [[adi>ADUM3190S|EVAL-ADUM3190S]] supports the ADuM3190s isolated error amplifier based on Analog Devices, Inc., iCoupler® technology. The [[adi>adum3190S|ADUM3190S]] is ideal for linear feedback power supplies with primary side controllers enabling improvements in transient response, power density, and stability as compared to commonly used optocoupler and shunt regulator solutions. Included in the [[adi>adum3190S|ADUM3190S]] is a wideband operational amplifier that can be used to set up a variety of commonly used power supply loop compensation techniques. The [[adi>adum3190S|ADUM3190S]] is fast enough to allow a feedback loop to react to fast transient conditions and over current conditions. Also included is a high accuracy 1.225 V reference to compare with the supply output set point. | The [[adi>ADUM3190S|EVAL-ADUM3190S]] supports the ADuM3190s isolated error amplifier based on Analog Devices, Inc., iCoupler® technology.

| For tests other than the accuracy tests, open the 680 Ω resistor connections by removing R5 and R7 (0 Ω), the C7 integrating capacitor, and the external wire connection made between GND1 and GND2. Once completed, other components may be added to the evaluation board per the schematic in Figure 2 to make circuits for other tests such as [[adi>adum3190S|ADUM3190S]] data sheet specifications for the op amp, reference, UVLO, output characteristics, or power supply. | For tests other than the accuracy tests, open the 680 Ω resistor connections by removing R5 and R7 (0 Ω), the C7 integrating capacitor, and the external wire connection made between GND1 and GND2.
