View Datasheet Manufacturer Site View Pricing & Stock

The ADuM3190 is an isolated error amplifier based on Analog Devices, Inc., iCoupler® technology. The ADuM3190 is ideal forlinear feedback power supplies. The primary side controllers ofthe ADuM3190 enable improvements in transient response,power density, and stability as compared to commonly usedoptocoupler and shunt regulator solutions.Unlike optocoupler-based solutions, which have an uncertaincurrent transfer ratio over lifetime and at high temperatures, theADuM3190 transfer function does not change over its lifetime,and it is stable over a wide temperature range of −40°C to +125°C.Included in the ADuM3190 is a wideband operational amplifierfor a variety of commonly used power supply loop compensationtechniques. The ADuM3190 is fast enough to allow a feedbackloop to react to fast transient conditions and overcurrent conditions.Also included is a high accuracy 1.225 V reference tocompare with the supply output setpoint.The ADuM3190 is packaged in a small 16-lead QSOP packagefor a 2.5 kV rms isolation voltage rating.
