The TPS5124EVM evaluation module (EVM) is a highly customizable Digital Power System Management Evaluation Module used for testing and evaluating DC/DC and AC/DC offline switching mode power supplies (SMPS). Through an easy-to-use GUI (Graphical User Interface), the TPS5124EVM allows users to easily and quickly get up and running with their own specific power management designs. Additionally, the TPS5124EVM has features like programmable switching frequency, various voltage outputs, on-chip monitoring and control functions, power-on sequencing, cycle-by-cycle current limitation, and others.

The TPS5124EVM is primarily used in the prototyping of SMPS applications as well as in research and development applications. It is suitable for many AC/DC power management systems which require different voltage outputs. The TPS5124EVM’s programmable switching frequency provides high efficiencies that are needed in offline AC/DC applications. It is also often used to test the performance of SMPSs in challenging environmental conditions.

The TPS5124EVM works by using its on-chip current limit and switching frequency control. During operation, the TPS5124EVM measures the peak current of the power rail. The on-chip current limit feature then limits the peak current to the desired threshold. The programmable switching frequency feature allows the TPS5124EVM to switch from one frequency to another in order to minimize power loss and give higher efficiencies. This also allows the unit to be adjusted according to a specific application.

The TPS5124EVM also has power supply sequencing capabilities. It features programmable power-on sequencing of different power rails, which is useful in multi-stage power management systems. This feature helps to ensure safe operation of SMPSs in system designs by allowing the right order of power-on and power-off times.

Another feature of the TPS5124EVM is its Cycle-by-Cycle Current Limitation (CCL) function. This feature helps to prevent current surges occurring when the power rail is switched off or the load is cycled on and off. The CCL function helps to limit the peak current when the load is increased or decreased, making power supply management more reliable and efficient.

The TPS5124EVM is a very versatile module that provides many features to make it suitable for DC/DC and AC/DC offline SMPS applications. It offers easy-to-use GUI, programmable switching frequency control, on-chip monitoring and control functions, power-on sequencing, cycle-by-cycle current limitation, and many others. All these features make the TPS5124EVM an ideal choice for prototyping, evaluation, and testing of SMPSs.
