The ADP1873-BL2-EVZ evaluation board from Analog Devices is a high input voltage, high step-down (synchronous rectification) converter featuring both DC/DC and AC/DC (Off-Line) switching power supply (SPS) capabilities. It is intended to help power system designers evaluate the operation and performance of the ADP1873 family devices.

The ADP1873-BL2-EVZ is ready to evaluate power systems that employ a wide variety of input and output voltages and input power levels. The board features an input voltage range of 6 V to 60 V, with a nominal 48 V input. This increased range allows designers to evaluate both low-voltage, high-current systems and high-voltage, low-current systems. Additionally, the board can provide an output voltage of 0.8 V to 48V with up to 15A of output current.

A typical application of the ADP1873-BL2-EVZ involves a multi-output design with several off-line power levels and short circuit protection. In this application, power is delivered from a single output device with multiple power domain control. The ADP1873-BL2-EVZ board has the capability to convert the input voltage into different output voltage levels. Thanks to the ADP1873\'s synchronous rectification technology, the board also minimizes power dissipation and improves efficiency.

The ADP1873-BL2-EVZ evaluation board adopts the average current-mode control topology, which limits output voltage ripple, maintains Vout at an accurate regulation voltage, and provides power supply stability and protection against short circuit events. The ADP1873 provides a complete protection scheme that includes input under voltage and over voltage protections, as well as other protection features such as peak current-limit, over-temperature, overload and reverse current protection.

In addition to its wide range of power regulation capabilities, the ADP1873-BL2-EVZ evaluation board features a full complement of board monitoring and control features. This includes an Enable pin to offer the user a three-state operating mode. There is also a trim output to allow the user to get the most from their system by fine-tuning its operating parameters. The ADP1873-BL2-EVZ evaluation board also features a programmable Soft Start feature to ensure a smooth start up and reduce the risk of inrush current.

The ADP1873-BL2-EVZ evaluation board is an ideal solution for designers seeking an easy-to-use, flexible platform to evaluate their switching power supply designs. Its wide range of input and output power capabilities, along with its extensive protection features, make it a great choice for any possible power application.
