**ADUM5020-5BRWZ: A 5 kV rms Isolated DC-to-DC Converter for Robust Industrial Power Supplies**

In the demanding environment of industrial automation, motor control, and process instrumentation, **reliable power isolation is paramount** for both system safety and data integrity. The ADUM5020-5BRWZ from Analog Devices stands out as a critical component designed to meet these rigorous challenges. This highly integrated, isolated DC-to-DC converter provides a complete solution for generating an isolated power domain from a non-isolated input supply.

The core of the ADUM5020-5BRWZ's value proposition is its **reinforced isolation rating of 5 kV rms**. This high level of isolation is certified according to major international safety standards, including UL, VDE, and CSA. It effectively protects sensitive low-voltage circuitry and system operators from dangerous high-voltage transients and ground potential differences that are common in industrial settings. By preventing fault propagation, it ensures the entire system operates safely and reliably.

Beyond its impressive isolation, the converter integrates key components to simplify design and save board space. It features **Analog Devices' proprietary iCoupler® technology**, which combines a DC-to-DC controller, a power transformer, and isolation in a single, compact 16-lead SOIC_W package. This high level of integration eliminates the need for designers to source and design with a separate discrete transformer, significantly reducing both design complexity and the overall bill of materials (BOM).

The device operates from a **wide input voltage range of 4.5 V to 5.5 V** and delivers a regulated, isolated 5 V output at up to 250 mA of current. This output is sufficient to power isolated interfaces, sensors, or gate drivers that require their own clean power supply. Furthermore, the ADUM5020-5BRWZ offers excellent regulation and low ripple, which is essential for the noise-sensitive analog and digital circuits often found in these applications. Its efficiency and thermal performance are optimized for industrial temperature ranges (-40°C to +105°C), ensuring stable operation even in harsh environments.

In application, the ADUM5020-5BRWZ is ideal for providing isolated power to other isolated components, such as isolated gate drivers (e.g., ADuM4135), isolated ADCs, and isolated interfaces like RS-485, CAN, or SPI. It is a cornerstone for building robust power architectures in solar inverters, industrial PLCs, and medical equipment, where safety and noise immunity cannot be compromised.

**ICGOODFIND**: The ADUM5020-5BRWZ is an exemplary solution for engineers seeking to **enhance system reliability and simplify the design of isolated power supplies**. Its certified high isolation, integrated design, and robust performance make it an indispensable component for any industrial application where safety and data integrity are critical.
