Isolated error amplifier for power-conversion feedback
The Analog Devices ADUM4190TRIZ-RL is an isolated error amplifier from the iCoupler series, combining galvanic isolation with an error amplifier in a single 16-SOIC wide-body package. It is designed specifically for feedback loop isolation in power conversion applications such as shunt regulators, linear power supplies, inverters, and UPS systems. The part is surface-mount, ROHS3 compliant, and carries an active lifecycle status.
What the 16-SOIC wide-body package means for the layout
The 16-SOIC package has a 7.50 mm body width, the wide-body variant that provides the creepage distance needed for reinforced isolation ratings. The land pattern matches the standard SOIC-16 wide footprint. The tape-and-reel (TR) and cut-tape (CT) packaging options cover both production reel and prototype quantities.
Target applications: where this isolator fits
The ADUM4190TRIZ-RL is specified for shunt regulators, linear power supplies, inverters, and UPS equipment. These are all topologies where the error amplifier must sense the output voltage on the secondary side and drive the primary-side PWM controller across an isolation barrier. Using an integrated isolator + error amplifier saves a separate optocoupler and shunt regulator pair.
