High Stability Isolated Error Amplifier

Data Sheet

ADuM4190

FEATURES

GENERAL DESCRIPTION

Stable over time and temperature

0.5% initial accuracy

1% accuracy over the full temperature range

The ADuM4190¹is 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

Compatible with Type II or Type III compensation networks

Reference voltage: 1.225 V

Compatible with DOSA

the ADuM4190 enable improvements in transient response, power

density, and stability as compared to commonly used optocoupler

and shunt regulator solutions.

Low power operation: <7 mA total

Wide voltage supply range

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.

_DD1: 3 V to 20 V

_DD2: 3 V to 20 V

Bandwidth: 400 kHz

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.

Isolation voltage: 5 kV rms reinforced

Safety and regulatory approvals (pending)

UL recognition: 5000 V rms for 1 minute per UL 1577

CSA Component Acceptance Notice #5A

VDE certificate of conformity

DIN V VDE V 0884-10 (VDE V 0884-10):2006-12

_IORM= 849 V peak

The ADuM4190 is packaged in a wide body, 16-lead SOIC package

for a reinforced 5 kV rms isolation voltage rating.

Wide temperature range

−40°C to +125°C ambient operation

150°C maximum junction temperature

APPLICATIONS

Linear feedback power supplies

Inverters

Uninterruptible power supplies (UPS)

DOSA-compatible modules
