ADUM3190ARWZ-RL7 Descripción general
An isolated error amplifier is a specialized amplifier that transfers an error signal across an isolation barrier without a direct electrical connection. It is a key component in isolated power supplies, where it compares the output voltage to a reference and sends the error signal to the primary-side controller. This enables regulation while maintaining galvanic isolation for safety and noise immunity.
Key features include a 1.225 V reference voltage, compatibility with Type II or Type III compensation networks, and low power operation of less than 7 mA total. The device supports a wide supply range of 3 V to 20 V on both VDD1 and VDD2, and provides 400 kHz bandwidth. It is available in a 16-lead SOIC-W package, offering a compact solution for isolated feedback.
The ADUM3190 uses iCoupler technology, which integrates micro-transformers to achieve isolation, eliminating the need for optocouplers and providing improved reliability and performance. The device is compatible with DOSA (Distributed-power Open Standards Alliance) standards, ensuring interoperability. It also meets safety approvals including UL 1577 and IEC/EN/CSA 62368-1.
Typical applications include shunt regulators, linear power supplies, inverters, and uninterruptible power supplies (UPS). The device is ideal for isolated feedback in AC-DC and DC-DC converters, where precise regulation and isolation are critical. Its wide supply range and low power consumption make it suitable for both industrial and consumer power systems.
When designing with the ADUM3190, ensure proper PCB layout to maintain isolation creepage and clearance distances. The device requires bypass capacitors on both supply pins to ensure stable operation. The reference voltage accuracy is critical for output regulation, so use precision resistors in the feedback network.

Notas de diseño
For 2.5 kV isolation, ensure PCB creepage and clearance distances meet UL 1577 requirements. Maintain at least 8 mm creepage between primary and secondary sides. Use a slot in the PCB under the isolator to enhance isolation performance.
Bypass VDD1 and VDD2 with 0.1 uF ceramic capacitors placed close to the pins. For noisy environments, add a 10 uF electrolytic capacitor in parallel. Ensure the supply voltage stays within 3 V to 20 V to avoid damage.
Do not exceed the absolute maximum ratings. The reference voltage accuracy is critical for output regulation; use 1% or better resistors in the feedback network. Ensure the compensation network is properly designed for stability, as incorrect compensation can cause oscillation.
