ADP2102-3-EVALZ is an evaluation board from Analog Devices that provides a comprehensive solution for designers who require control circuit design. The evaluation board addresses all aspects of the design and implementation of DC/DC and AC/DC (off-line) switch-mode power supplies (SMPS) from solutions up to 25W. The board’s components are adjustable and the evaluation board has the capability to regulate, limit, or adjust the SMPS output power between 0.1W and 25W.

ADP2102-3-Evalz is suited for applications where DC/DC and AC/DC (off-line) switch-mode power supplies are necessary. This includes high current applications such as industrial, medical and networking, as well as low current applications such as consumer electronic product and LCD displays. ADP2102-3-Evalz helps designers by providing the necessary components, which includes a power supply controller, discrete components, and a board containing an onboard microcontroller, enabling designers to simulate various SMPS parameters for a wide range of output powers.

ADP2102-3-Evalz\'s power supply operation is based on the Buck/Boost converter control topology. This topology includes a linear controller with a dual mode PWM/PFM control loop, which is used to control both the input and the output stages of the SMPS. The PFM mode is used when the output voltage is above nominal, converting the output power to a PWM form. This feature ensures that the output voltage remains stable despite changes in the line voltage or in the load.

The evaluation board also features an adjustable switching frequency up to 500 kHz, which is ideal for higher power applications. For applications that demand high efficiency, the board is equipped with an advanced multi-phase synchronization feature that helps reduce both input voltage ripple and switching losses. Additionally, the board also features adjustable current limit and on-board thermal monitoring which enhances reliability and safety.

ADP2102-3-Evalz provides designers with an effective and efficient way of simulating various SMPS parameters for a wide range of output powers. The evaluation board also features high frequency operation, adjustable current limit, and thermal monitoring, providing designers with the necessary tools to design and simulate various solutions. Through the evaluation board\'s comprehensive solution and supporting features, designers can easily develop, test, and deploy DC/DC and AC/DC (off-line) switch-mode power supplies.
