The EVAL-ADuM3190S supports the ADuM3190S Space Grade isolated error amplifier based on Analog Devices, Inc. iCoupler® technology. The 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 ADuM3190S is a wide band operational amplifier which can be used to set up a variety of commonly used power supply loop compensation techniques. The 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 1.225V reference to compare with the supply output set point.
