The ADP1874-0.3-EVALZ evaluation board is part of a large family of DC-DC & AC-DC SMPS (switched mode power supply) evaluation boards. It provides designers with an efficient way to evaluate the features and performance of the ADP1874, a dual-channel control IC designed for the dual-channel flyback power topology. The evaluation board is specifically designed to support power applications with an output voltage up to 32-V (300-W).

The evaluation board’s hardware design follows the guidelines recommended by the 3rd edition of the CPU-T specs. Consequently, the board provides a high-efficiency, safe, and cost-effective solution for various power applications. In addition, the board also provides easy and convenient access to monitoring and control pins to quickly and accurately develop DC-DC & AC-DC SMPS.

The board includes a number of features such as two identical isolated channels, an auto-tuning circuit, and a power section. The two channels on the board are controlled by two ADP1874 dual-channel controllers, to enable partial or complete parallel operation. The auto-tuning circuit is designed to minimize additional parameter adjustment and thus minimize the time required for the board to reach its stable operating conditions.The power section contains a transformer, two sets of rectifiers/diodes, and two DC output wires to connect to the load.

The ADP1874-0.3-EVALZ evaluation board supports a variety of input supply configurations, including single-phase AC (230V-415VAC) and DC (10-80V). Additionally, the board supports dual-phase AC (230V-480VAC) inputs. The board also has up to eight input voltage presets, allowing it to be used in multiple applications. The board also has a low ripple factor and short start-up time, making it suitable for applications with low voltage and power demands.

The ADP1874-0.3-EVALZ evaluation board also provides various protections, including over-voltage, over-current, and short-circuit protection. In addition, the board also has a series of LED indicators to provide information about the status of the board. Other features of the board include temperature measurement and monitoring capabilities.

Overall, the ADP1874-0.3-EVALZ evaluation board is an efficient and reliable way to evaluate the performance and features of the ADP1874 dual-channel control IC for dual-channel flyback power applications. It provides designers with a comprehensive set of features for testing and evaluation of the various DC-DC & AC-DC SMPS designs.
