ADUM4190 Product Details

The ADuM4190 is an isolated error amplifier based on Analog Devices, Inc. iCoupler� technology. The ADuM4190 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. Unlike optocoupler-based solutions, which have an uncertain current-transfer-ratio over lifetime and at high temperatures, the ADuM4190 transfer function does not change over lifetime and is stable over a wide temperature range of -40�C to 125�C. Included is a wide band operational amplifier which can be used to set up a variety of commonly used power supply loop compensation techniques. The ADuM4190 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.
