The ADuM4190 is an isolated error amplifier based on ADI, iCoupler® technology. The ADuM4190 is ideal forlinear feedback power supplies. The primary side controllers ofthe ADuM4190 enable improvements in transient response, powerdensity, and stability as compared to commonly used optocouplerand shunt regulator solutions.Unlike optocoupler-based solutions, which have an uncertaincurrent transfer ratio over lifetime and at high temperatures, theADuM4190 transfer function does not change over its lifetimeand is stable over a wide temperature range of −40°C to +125°C.Included in the ADuM4190 is a wideband operational amplifierfor a variety of commonly used power supply loop compensationtechniques. The ADuM4190 is fast enough to allow a feedback loopto react to fast transient conditions and overcurrent conditions.Also included is a high accuracy 1.225 V reference to comparewith the supply output setpoint.The ADuM4190 is packaged in a wide body, 16-lead SOIC packagefor a reinforced 5 kV rms isolation voltage rating.
