ADP5304-EVALZ is an evaluation board for low power switching regulators. It is designed to evaluate the functionality of the ADP5304, a monolithic synchronous step-down switch mode power supply with integrated MOSFETs. The evaluation board includes a number of components and features that make it suitable for a wide range of applications, such as in AC/DC and DC/DC power supplies.

The ADP5304 is a high-efficiency, constant frequency synchronous control step-down DC/DC regulator. It is designed to provide a regulated output over a wide input voltage range with excellent line and load regulation. The part contains an internal oscillator that is factory programmed for a fixed switching frequency adjustment range of from 300kHz to 600kHz.

The ADP5304-EVALZ has two operating modes: continuous and switch-mode. In continuous mode, the board operates in continuous conduction mode (CCM). This allows for constant current output with a maximum output current allowing for heavy load transients. The other mode, switch-mode, allows for efficiency optimization and interleaving. In interleaving, multiple outputs ripple together and supply a load with a constant KVA power supply that minimizes audible noise.

The ADP5304-EVALZ evaluation board has a number of features and components that make it suitable for applications in AC/DC and DC/DC power supplies. The board includes a surface mount MOSFET, a third-order loop filter, and a voltage divider for feedback regulation. In addition, the board includes an open loop sensing circuit that allows for monitoring of the input voltage as well as the output current. The board also includes an on-board temperature sensor that can be used to monitor the temperature of the operating environment.

The board is designed to accept any input voltage between 5.5V and 20V, and can output up to an 8.6A maximum current. The output voltage can be adjusted from 0.6V to 5V. The board can operate in either discontinuous or continuous modes, allowing for optimization of efficiency and performance. The board can also be configured to support interleaving functionality and on-board sensing.

The ADP5304-EVALZ is an ideal evaluation board for the design of low-power switching regulators. With its wide input voltage range and maximum output current of 8.6A, the board supports a wide range of applications. Additionally, with its integrated temperature sensor, interleaving feature, and on-board sensing, the ADP5304-EVALZ is suitable for use in AC/DC and DC/DC power supply applications.
