Product Overview

The EVAL-ADUM3190EBZ is an evaluation board for ADuM3190 isolated error amplifier based on iCoupler technology. The ADuM3190 is ideal for linear feedback power supplies with primary side controllers enabling improvements in transient response, power density and stability as compared to commonly used optocoupler and shunt regulator solutions. Included in the ADuM3190 is a wideband operational amplifier that can be used to set up 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 set point. 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 lifetime and is stable over a wide temperature range of -40°C to 125°C.
