Linear voltage regulators are important when it comes to providing a steady voltage for processing, communications, power management and control. The TPS799XXEVM-105 Evaluation Board from Texas Instruments is a linear voltage regulator with a load switch that is suitable for a variety of load regulation in consumer, industrial and automotive applications.

The evaluation board has a power supply, an analog voltage control loop and a load switch. The power supply provides an adjustable, regulated output voltage from 1.2V to 18V and features an input voltage range from 6.5V to 18V. Its output current can be limited up to 2A and the load switch has an adjustable push-pull logic level output. It features under-voltage, over-voltage and over-current protection, with a low 220mV dropout voltage.

The board is designed to support 3mm x 3mm micro SMD packages. It also has an integrated power path controller with I2C interface for on-board configuration and status signals. The board also features a high-speed ADC and DAC for device evaluation, and has the option to enable and disable the load switch through an I2C Measurement and Control Unit.

The working principle of the TPS799XXEVM-105 Evaluation Board is that it converts an input voltage into a precise and efficient regulated output voltage. This is done by the analog voltage control loop inside the board. The error amplifier takes the difference between the output voltage and a voltage reference as its input. This difference voltage is amplified and is used to adjust the output voltage until it reaches the reference voltage and a steady state is achieved. This regulated output voltage is then used to power the load switch to control the load conditions.

The TPS799XXEVM-105 Evaluation Board is suitable for a variety of applications such as automotive regulatory and control, consumer electronics such as mobile phones, gaming systems, home entertainment systems, computers and other consumer devices. In addition, the board can be used for industrial and medical equipment, as well as for telecommunications, networking and power supplies where precise voltage and current regulation is required.

The TPS799XXEVM-105 Evaluation Board is a useful and convenient tool for evaluating the performance of any configured linear voltage regulator and can be used to optimize the output voltage, current limit and load conditions to suit the application’s requirements. Moreover, by using the mbed platform, users can easily evaluate the performance of the board and configure its parameters, such as the output voltage and current limit.
