The EVAL-ADUM5028EBZ is a highly advanced evaluation board for dual-channel isolators in the power supply market. It can be used for both DC/DC and AC/DC (off-line) SMPS (switched mode power supply) applications.

The EVAL-ADUM5028EBZ is based on Analog Devices’ ADuM5028 isolation system. This system is based on the latest gallium-nitride-on-silicon (GaN-on-Si) technology, which provides enhanced thermal properties, allowing the device to operate efficiently and reliably at higher temperature. It provides excellent isolation voltage of up to 3000Vrms and low ON-resistance (<350Ω). This makes it suitable for high-performance power isolation applications.

The evaluation board provides an easy-to-use platform for testing the performance of the ADuM5028 isolator and designing custom isolated power supplies. The board includes two isolated channels — each channel providing two AC/DC and one DC/DC output. The onboard controllers and evaluation features make the board an ideal platform for testing and prototyping.

The EVAL-ADUM5028EBZ evaluation board also includes an on-board debug interface for easy programming and communicating with the board. The interface allows the user to customize the board\'s behavior by changing parameters such as the frequency, duty cycle, and isolation voltage. Additionally, the board includes various signals to alert the user of the board\'s status.

The EVAL-ADUM5028EBZ evaluation board includes a range of protection against failure or over-voltage. It provides protection against reverse current direction, over-current, over-voltage and over-temperature. Additionally, the board includes redundant channels, allowing it to detect any failures or abnormalities in one channel and automatically switching to the other backup. This ensures the board’s continued operation and safety when powered up.

In addition to providing development support for the ADuM5028 dual-channel isolator, the board also provides other features such as integrated load regulation, comprehensive voltage supervision, SPI communications and on-board EEPROM memory. This provides great flexibility for developing power supplies and other isolated applications.

In conclusion, the EVAL-ADUM5028EBZ evaluation board is a great tool for testing and developing applications that require dual-channel isolation. The board provides an easy-to-use platform that is integrated with all the features needed to create an efficient and reliable power supply.
