**ADUM5028-5BRIZ: A 5 kV Isolated, 3 V to 5 V Output DC-DC Converter**

In the realm of modern electronics, achieving reliable power isolation is a critical challenge, especially in applications where safety, noise immunity, and voltage level shifting are paramount. The **ADUM5028-5BRIZ** stands out as a specialized solution, integrating a **5 kV isolated, DC-DC converter** capable of delivering a regulated 5 V output from an input as low as 3 V. This device is engineered to address the stringent requirements of industrial automation, medical equipment, and communication interfaces, where high-voltage separation between system domains is non-negotiable.

Leveraging **Analog Devices' proprietary iCoupler® technology**, the ADUM5028-5BRIZ combines a DC-DC converter with galvanic isolation in a compact, surface-mount package. This integration eliminates the need for separate isolation components, simplifying board design and reducing overall system size. The converter operates with high efficiency, minimizing heat generation and ensuring reliable performance in space-constrained environments. Its ability to operate from a **3 V input** makes it exceptionally suited for low-power applications, including battery-powered systems or circuits driven by microcontrollers with limited supply rails.

The **5 kV isolation rating** provides a robust barrier against high-voltage transients, enhancing system safety and compliance with international standards such as IEC 61010-1 and IEC 60601-1. This makes the device ideal for protecting sensitive low-voltage circuitry from high-voltage sections in medical devices or industrial control systems. Additionally, the regulated 5 V output ensures stability even under varying load conditions, critical for powering analog sensors, digital logic, or isolated communication interfaces like RS-485 or CAN.

Noise suppression is another key advantage. The device’s design minimizes electromagnetic interference (EMI), reducing the risk of noise coupling across the isolation barrier. This is particularly valuable in precision measurement applications where signal integrity is crucial.

**ICGOODFIND**: The ADUM5028-5BRIZ integrates isolation and power conversion into a single, efficient solution, offering designers a reliable way to achieve high-voltage separation with minimal footprint. Its low input voltage capability and high isolation rating make it a versatile choice for demanding applications across industries.
