Product Description
ADUM3190ARQZ-RL7
A high isolation, automotive-grade temperature range isolated error amplifier, widely used in isolated power supplies, inverters, and automotive power management systems.
Product Overview
The ADUM3190ARQZ-RL7 is an isolated error amplifier based on Analog Devices' iCoupler® technology, designed for linear feedback power supplies with primary-side controllers. It outperforms traditional optocoupler + shunt regulator solutions in transient response, power density, and long-term stability.
Key Functions
Isolated Error Amplifier
Replaces optocouplers and shunt regulators to provide stable, isolated feedback without aging or temperature drift issues.
