ADuM3190/4190 Isolated Error Amplifier

Analog Devices Inc. ADuM3190/4190 High Stability Isolated Error Amplifier is based on ADI iCoupler® technology and is ideal for linear feedback power supplies with primary side controllers. This technology enables 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, ADuM3190/4190's transfer function does not change over lifetime and is stable over a wide temperature range of -40°C to 125°C.
