The TPS54719EVM-152 is a power-supply evaluation board designed for bothAC and DC DC applications, allowing users to test different power supply solutions. It is the ideal platform for application development and evaluation of power design in the DC/DC and AC/DC (Off-Line) SMPS fields.

The TPS54719EVM-152 board consists of two main parts: the power-supply circuit and the user interface. The power-supply circuit consists of the TPS54719CSL Multi-Function D-CAP Mode Phase Shifted Full-Bridge PWM controller, two Low-Side Switches with integrated circuits, and two DC-DC converters, designed to optimize efficiency. The power-supply circuit is expandable and allows the user to implement and test different power device leads and configurations.

The board is highly configurable, allowing different configurations and user settings. The evaluation board can be used to evaluate both open loop and closed loop operation. The board allows the user to set the output voltage, the current limit, and the switching frequency. A control loop is included to optimize output voltage. Additionally, an analog input can be used to fine-tune the voltage setpoint and prevent over- or under-shooting.

The TPS54719EVM-152 evaluation board has several safety features, such as under-voltage protection and over-temperature protection, to ensure proper operation in most environmental conditions. The board also has a circuit breaker for fault protection, and two LEDs to indicate the power supply’s status. An RS-232 interface is included for communication and data logging, as well as other features which can be used for debugging, such as an oscilloscope trigger.

The board operates in open loop or closed loop control. In open loop operation, the user sets the desired output voltage and current limit. The user can also set a switching frequency up to 400kHz, and the board can operate in either continuous or pulse width modulation (PWM) mode. In closed loop operation, the user sets the desired output voltage, and the control loop will adjust the output voltage as required.

The TPS54719EVM-152 evaluation board is ideal for DC/DC and AC/DC (Off-Line) SMPS applications, and is highly configurable with safety features to ensure proper operation. It allows the user to evaluate different power supply solutions, and can operate in either open or closed loop control. With its user interface and wide range of features, the TPS54719EVM-152 evaluation board is an ideal platform for power supply application development and evaluation.
