ADP1872-BL1-EVZ is a type of Evaluation Boards - DC/DC & AC/DC (Off-Line) SMPS. It is specifically designed to provide an evaluation platform to conveniently evaluate on-line, DC/DC and AC/DC, off-line SMPS devices. It also has a wide range of applications, such as socket power supplies, PC PSU, LCD TV adapters, as well as various other power supply applications.

This evaluation board is a standard switching power supply board with a power range of 3.2V to 28V. It comes with a wide range of components for optimal performance, including a step-down switch, inductor, capacitor, active PFC filter, EMI filter, EFT filter and surge protection devices. Furthermore, it is also equipped with a USB micro-B connector, solar panel illustration, programmable power output, power output voltage options, and some thermal protectors.

The ADP1872-BL1-EVZ board is controlled by an MCU chip that enables full communication through USB port. It also provides a continuous output current of 1A for the AC/DC off-line SMPS applications. The board can be used in both DC or AC applications, and it is capable of delivering an output power range of 3W-60W.

ADP1872-BL1-EVZ has a wide operating range from 4.5V to 24V. It also features an efficiency up to 97% for different voltage conditions and provides up to 0.3A output current regulation. Moreover, it has an output short-circuit protection and inrush current control to prevent the system from damage. Additionally, it also provides protection with input transient and overload protection.

This evaluation board works by utilizing integrated power stage with a PFC and synchronous buck converter. The PFC stage uses an Active PFC which works to reduce the total harmonic distortion. It works by rectifying an AC waveform coming from the receptacle and storing the energy in capacitors, then syncing the voltage buck converter by using an Opto-coupler. This then buck-converts the voltage to the desired output voltage, before it is further rectified by an active PFC stage and then delivered to the load.

In summary, ADP1872-BL1-EVZ is a type of Evaluation Boards - DC/DC & AC/DC (Off-Line) SMPS. It is designed to be a versatile, full featured power supply platform for various applications. It is capable of providing a high efficiency, high power output up to 60W and accepts a wide 4.5V to 24V operating range while providing optimal protection for the system. Additionally, the evaluation board has an integrated PFC and synchronous buck converter, and the output voltage can be programmable with USB communication.
