The DC266B-B is a high-performance, cost-effective evaluation and demonstration board and kit from Texas Instruments. This board is designed to quickly and easily evaluate and demonstrate a variety of applications, such as low-power voltage reference circuits, DC/DC converters, switching regulators, and precision DACs. It is equipped with user-friendly features such as selectable power supply, digital display, rotary switch, and LED indicators to enable quick and easy setup. The board also provides an array of ports, including a USB port, Arduino headers, I2C, SPI, and UART, for connecting external components and programming the board in various ways.

The DC266B-B is designed for a wide variety of applications. Output accuracy can be maintained up to 70% load with very low noise and power dissipation. The integrated onboard amplifier allows the board to provide low-power output signals for testing microcontrollers and digital circuits. The board also supports 10-bit resolution Digital to Analog converting, making it suitable for creating waveforms and testing various DACs.

The DC266B-B board can operate from either a DC power supply or AC power supply. It has a precision voltage reference circuit, which can be used to accurately set the voltage output, and it also includes a precision current converter for setting up a current limit. A user-friendly graphical user interface provides convenient control over all the features of the board.

The DC266B-B board has an adjustable switching frequency, allowing for easy adjustment of the output. It also has a soft-start function, which allows for fast start-up and shut-down of the board with no overshoot. The board also includes a unique, user-selectable level shifter option which can be used for analog output, providing extra flexibility when using multiple output levels.

The DC266B-B works on the principle of pulse-width modulation (PWM). PWM is a technique for controlling an output by switching it between two levels at fixed frequencies, thus modulating the amount of time the output is at one level or the other. This technique allows for fast and efficient control of the output voltage. The board can also operate in either open-loop or closed-loop mode, depending on the application.

The DC266B-B board is designed to provide reliable and cost-effective solutions for a wide range of applications. Its features, including on-board amplifier, adjustable switching frequency, soft-start, and level shifter make it suitable for various types of applications in the industrial, automotive, communication, medical, and consumer markets. Furthermore, the board is highly customizable, making it easy to use and set up.
