Evaluation boards offer a great way to quickly test and evaluate a product or design before commercializing it. They provide an interface between the designer and the product to allow efficient testing and quickly optimize the design. TPSM84A21EVM-808 is an evaluation board which provides an example implementation of Texas Instruments’ TPSM84A21 step-down converter. This evaluation board enables development, demonstration, and performance verification of a synchronous step-down, high-efficiency, non-isolated DC/DC converter.

The TPSM84A21 synchronous buck converter evaluation board consists of an on-board TPSM84A21 control IC which is connected to a buck converter power stage. The control loop for the power stage is built with the TPSM84A21. The on-board TPSM84A21 acts as the main controller, driving a high-side MOSFET and a low-side MOSFET. The buck converter power stage is connected to two Flyback-type transformers, and integrated circuit to provide feedback control and protection.

The DC/DC converter evaluation board operates in critical conduction mode with high switching frequency of 1.2 to 2 MHz to achieve compact size, low switching losses, and high efficiency. The TPSM84A21 also features PFM/PWM auto-shift, built-in boost diode, adjustable Soft Start, built-in Level Shift logic, turn-off logic and so on. The control IC’s integrated detection circuits allow for output UVLO, OVP, and OCP protection, while other protection features include rough handling protection functions.

The power stage of TPSM84A21 evaluation board can deliver up to 10A output current. The TPSM84A21EVM-808 evaluation board can be set to any output voltage from 1.2V up to 12V. Synchronization is supported, as well as the selection of several PFC options (ocppfc, OCP, OVP, PFP/PFM, etc.) for the operation.

The TPSM84A21EVM-808 evaluation board is a great tool for designers and engineers to quickly optimize a power converter design. The evaluation board includes features that are not available on any other evaluation board and allows designers to experiment with a variety of solutions for a wide range of applications.

The evaluation board offers a great way to quickly test and evaluate different power design implementations before commercializing them. It provides a platform for designers to explore different power designs and adjust parameters for maximum optimization. With the demonstration and performance evaluation capability of the TPSM84A21EVM-808, designers can quickly and efficiently develop and optimize their power designs.

The evaluation board allows the user to experiment with a wide range of application scenarios such as power management for mobile devices, consumer electronics, automotive, industrial, and medical applications. The evaluation board can also be used to evaluate several applications such as lighting, renewable power sources, and machine-to-machine communication. TPSM84A21EVM-808 can deliver high-current, low-voltage output for any application, and is ideal for power conversion applications requiring high-efficiency and tight DC output regulation.

In summary, the TPSM84A21EVM-808 evaluation board offers an efficient and cost-effective way for designers to quickly optimize the power design of their products. The evaluation board includes features that enable designers to quickly develop power designs for applications with high-current output and to make necessary parameter adjustments for maximum optimization.
