The ADUM4190BRIZ is a high stability Isolated Error Amplifier with iCoupler® technology. The ADuM4190 is ideal for linear feedback power supplies. The primary side controllers of the ADuM4190 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 ADuM4190 transfer function does not change over its lifetime and is stable over a wide temperature range of -40 to +125°C. Included in the ADuM4190 is a wideband op-amp for 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 overcurrent conditions. Also included is a high accuracy 1.225V reference to compare with the supply output setpoint.
● Compatible with Type II or Type III compensation networks
● Compatible with DOSA
● <7mA Total low power operation
● 150°C Maximum junction temperature
