The ADP1871-BL2-EVZ is an evaluation board that allows users to accurately adjust a buck converter for a wide variety of application fields. This evaluation board is a DC/DC & AC/DC (Off-Line) SMPS which provides a precision reference to control the output voltage of buck converters. This board provides a step-by-step guide during the configuration of buck converters. With the adjustable input and output voltages, users can precisely set the output voltage to meet their specific requirements.

The ADP1871-BL2-EVZ is designed with a current-mode PWM controller that delivers high performance and accurate tracking of the output voltage. This application board can be used to evaluate and adjust buck converters in a wide range of application fields. It is equipped with a soft-start feature that eliminates the inrush current when powering up the converters, making it suitable for automotive, industrial, and consumer applications. It also provides a user-selectable power-good and current limit functions for verification of output voltage and current.

The working principle of the ADP1871-BL2-EVZ evaluation board is based on the principle of buck conversion. This board converts a higher input voltage to a lower output voltage through an integrated PWM controller. The input voltage is connected in series to the inductor, while the output voltage is connected to the load across the switch. Through adjusting the switch duty cycle, the output voltage is controlled and the current limit is set. When the switch is closed, the inductor stores energy by taking current from the input, and when the switch is opened, the stored energy is transferred to the output.

The ADP1871-BL2-EVZ evaluation board is a great tool for evaluating and adjusting buck converter applications. This board provides precision voltage and current regulation to meet user requirements. With adjustable input and output voltage, the board allows users to accurately set their output voltage. The user-selectable power good and current limit functions provide verification of output voltage and current. It is suitable for applications in a wide range of industries such as automotive, industrial, and consumer.
