Evaluation Boards - DC/DC & AC/DC (Off-Line) SMPS offers many tools to support various power conversion tasks. The TPS548B22EVM-847 evaluation module (EVM) is one of them and is designed to evaluate the performance of TPS548B22, a 5-A, Buck Converter.

The TPS548B22EVM-847 is for an adjustable SEPIC/Buck application but can be configured for other topologies too. It offers general power conversion experimental operations including synchronous step-down DC/DC converter, LED driving application, asymmetrical and synchronous step-down DC/DC converters, and so on. It also supports a wide range of input and output voltages, and allows the user to easily implement all kinds of power conversion strategies.

The TPS548B22EVM-847 comes in a 4x4 mm package and includes all necessary external components. It has two boards, one for host and the other for the evaluation circuit. The evaluation board includes an LED to indicate power status, two switches (EN1 and EN2) that control the output voltage, a temperature sensing NTC thermistor (NTC1), and a POT (Trim Pot) that adjusts the output voltage. The On-Board 5-pin header connector, J6, provides user access to the signals for external monitoring of voltages, currents and switching waveforms. The On-Board 4-pin J7 enables the connection of the external current sense resistor and external output load.

The EVM allows for the evaluation of a wide range of input voltage, output voltage, and load current requirements. It also allows for the configuration of different topologies and various power conversion strategies. The evaluation circuit has two external power sources, one supplied to the primary side and the other to the secondary side. An output filter is also included in the circuit which consists of an L-C snubber network.

The TPS548B22EVM-847 has an easy-to-use graphical user interface (GUI) for parameter control, monitoring, and debugging. The GUI can control the supply voltage, output voltage, load current, and other settings. User can also program the P-PHASE enable/disable functions and set the optimum operating parameters for various applications.

The TPS548B22EVM-847 allows for the efficient testing of the buck converter. The device can operate over a wide range of input voltage and output voltage, and can support different load current requirements. It also allows for the evaluation of different power conversion strategies utilizing different topologies of the buck converter. The evaluation board is designed to simplify the evaluation process and ensure that the device can be tested thoroughly and efficiently.
