Evaluation and Demonstration Boards and Kits

TPS2113AEVM-061 is an evaluation and demonstration board designed for the Texas Instruments TPS2113A low-side power switch. The board offers a platform to evaluate the performance of the TPS2113A in circuit designs.

Application Field

The primary application field of TPS2113AEVM-061 is in design and testing of systems utilizing the TPS2113A switch. It offers a simple, but complete platform for the user to evaluate the switch performance with real world loads. It can be used to evaluate the device switching performance, ability to survive transients, current limit accuracy, and general reliability testing.

The board can also be utilized for the evaluation of other application specific requirements. It can be used to evaluate the capability of the TPS2113A device to interface with different devices and their circuitry. It Proves to be useful in power supply design, motor control, load control, multi-rail power management, and DSP-based control applications.

Working Principle

The board features a load resistor that can be changed manually or remotely controlled via the board’s TRK connectors. The load resistor is connected to a dual power supply; one input is signifying ground voltage and the other a higher voltage. The following diagram provides an overview of the board layout.

The TPS2113A is powered separately from the load, and its input is connected to the dual power supply. The output of the TPS2113A is connected to one of the load resistors, and the other is connected to the ground voltage. To control the operation of the TPS2113A, the logic control signal is connected directly to its input. The board also features a current limit adjustment switch that can be used to adjust the current limit of the TPS2113A.

When the TPS2113A is operational, the current passes through the load resistor, producing a voltage drop. This voltage drop is measured across the resistors and can be used for performance evaluation purposes. The device is also capable of surviving transients and offers a wide operating range when the current limit is adjusted. In addition, the board provides the user with LEDs which indicate various control signals, load status and other status indicators. The board also offers protection for the TPS2113A device from over-current and over-temperature conditions.

Conclusion

The TPS2113AEVM-061 board is a versatile platform which enables users to evaluate the performance of the TPS2113A switch. It offers the user a complete platform to test the device in real world application scenarios. The board also has proven successful in capturing application specific requirements for power supply design, motor control, load control, and multi-rail power management applications.
