The ADUM3190ARQZ is a High Stability Isolated Error Amplifier based on iCoupler® technology. It is ideal for linear feedback power supplies. The primary side controllers enable 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 ADUM3190 transfer function does not change over its lifetime and it is stable over a wide temperature range of -40 to +125°C. Included in the ADUM3190 is a wideband operational amplifier for a variety of commonly used power supply loop compensation techniques. The ADUM3190 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 setpoint.
