TPS40055EVM-001 is an evaluation board used to evaluate the performance of the TPS40055 boost converter in a variety of applications. The TPS40055 is a 600-V, 4-A rated, synchronous variable frequency controller with adjustable current limit, allowing for a maximum output voltage of 70 V. It is also capable of providing up to 100 kHz switching frequency for very efficient operation.

The TPS40055EVM-001 application field is ideal for a range of energy-related applications, such as solar photovoltaic (PV) systems, DC-to-DC converters, LED lighting, motor drives, power conditioners, and battery management systems. It is also suitable for both battery operated and ac/dc power applications, making it a versatile board for all types of applications.

The TPS40055EVM-001 is also fully configurable via the on-board LCD or web-based GUI. This allows for quick and easy adjustment of parameters, such as PWM frequency, voltage, current limit, overvoltage protection (OVP), and over current protection (OCP). The graphical user interface (GUI) also supports basic operating modes, such as constant voltage mode (CV), constant power mode (CP) and constant frequency mode (CF).

The TPS40055EVM-001 works by using a PWM control technique, which allows it to produce a regulated output voltage from an unregulated supply. This is achieved by switching the boost converter on and off at a rapid rate, which produces a high-frequency ‘chopping’ of the input voltage. This chopped signal is then fed through an internal filter, which produces a series of very short ‘on’ and ‘off’ periods. This constant switching of the ‘on’ and ‘off’ states is used to regulate the output voltage to a set point. The controller is capable of operating at switching frequencies up to 100kHz, which is much faster than traditional boost converters.

The TPS40055EVM-001 also features an onboard current-sensing circuit, which allows the user to adjust the current limit based on the input voltage. This allows for a more precise current limit setting, which can be adjusted in response to any changes in input voltage. This feature can be used to help reduce power losses due to over current or over voltage, and helps to ensure the highest efficiency throughout the application.

In addition, the TPS40055EVM-001 has several pre-programmed features to ensure safe and efficient operation. These include thermal protection, over temperature protection, over-current protection, over-voltage protection, and under-voltage protection. The board also includes a number of advanced features, such as an on-board oscilloscope, voltage transient suppression, and a programmable software interface. All of these features help to ensure that the board runs smoothly and at the highest possible efficiency.

The TPS40055EVM-001 EVM is a versatile and efficient board for DC/DC and AC/DC (off-line) SMPS applications. It provides a wide range of adjustable parameters for both battery operated and ac/dc power applications. With its high switching frequency, adjustable current limit, voltage transient protection, and onboard oscilloscope, the evaluation board ensures the highest efficiency for any application. It is also pre-programmed with a number of features to ensure safe and reliable operation, making it an ideal choice for any power-related project.
