GENERAL DESCRIPTION
The ADuM41901 is an isolated error amplifier based on Analog
Devices, Inc., 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°C to +125°C.
Included in the ADuM4190 is a wideband operational amplifier
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 1.225 V reference to compare
with the supply output setpoint.
The ADuM4190 is packaged in a wide body, 16-lead SOIC package
for a reinforced 5 kV rms isolation voltage rating.

1 Output gain is defined as the slope of the best-fit line of the output voltage vs. the input voltage over the specified input range, with the offset error adjusted out.
2 Output linearity is defined as the peak-to-peak output deviation from the best-fit line of the output gain, expressed as a percentage of the full-scale output voltage.
