TPS6218xEVM-581 is an evaluation module (EVM) designed by Texas Instruments (TI) to evaluate their TPS6218x XLPE pulsed switch DC/DC low-cost offline (AC/DC) power supply (SMPS) controllers— namely, TPS621802, TPS621804, TPS621808, and TPS621812. The EVM provides adjustable output voltage capabilities and is capable of generating a broad range of output current levels (from 0.5 to 4A) from an input voltage of 92 to 280V AC.

The EVM board comes preloaded with all necessary components, such as integrated power-switch MOSFETs, the controller IC, optoisolator, and other support components. It enables user to evaluate the system quickly and accurately without the need for a full power supply design. The evaluation board features all necessary components to develop a working prototype of an offline SMPS with adjustable output voltage and current levels.

The working principle of the TPS6218xEVM-581 includes a main feedback loop, a secondary loop, an optoisolator, a pair of transistors, a few resistors and capacitors, and integrated power switch MOSFET. The controller IC is the brain of the EVM and is responsible for driving all of the other components. It monitors the input voltage, output load, and other system parameters, and adjusts the output voltage accordingly. The output voltage is then regulated by the optoisolator and feedback loop, and the power switch MOSFETs are used to adjust the current level.

The TPS6218xEVM-581 is ideal for evaluating a wide range of offline switch-mode power supply applications that require adjustable output voltage and current levels. Applications include industrial, automotive, and consumer products for a variety of output DC/AC/DC power supply requirements. The board is compatible with 92 to 280V AC inputs, and is capable of delivering outputs that range from 0.5A to 4A. It also features over-temperature protection, over-load protection, and short circuit protection.

In summary, the TPS6218xEVM-581 is an evaluation board designed by TI to evaluate their TPS6218x XLPE pulsed switch DC/DC low-cost offline (AC/DC) power supply (SMPS) controllers. It is ideal for evaluating a wide range of offline switch-mode power supply applications that require adjustable output voltage and current levels. Examples include industrial, automotive, and consumer products for a variety of output DC/AC/DC power supply requirements. The board features over-temperature protection, over-load protection, and short circuit protection.
