    ADuM3190It is with Analog DevicesiIsolation error amplifier for Coupler® technology. The ADuM3190 is ideal for linear feedback supplies with primary-side controllers, offering improved transient response, power density, and stability compared to commonly used optocoupler and shunt regulator solutions.

    Unlike optocoupler-based solutions that have an uncertain current transfer ratio over the lifetime and at high temperatures, the ADuM3190's transmission function does not change over life and is stable over a wide temperature range of -40°C to 125°C.

    It has a built-in wideband op amp that can be used to set up a variety of common power loop compensation techniques. The ADuM3190 is fast enough to allow the feedback loop to react to fast transient regulation and overcurrent conditions. The device also includes a high accuracy 1.225V reference that can be compared to the power supply output set point.

    The ADuM3190 is available in a small QSOP-16 package (2.5kVrms).
