The DC2166A Evaluation Board from Tektronix is a versatile development platform designed for the evaluation of offline AC/DC or DC/DC SMPS circuits. The Evaluation board can be operated in either a buck or boost-converter configuration and can be used to test a wide range of SMPS solutions. The evaluation board provides an indication of the design performance, including transient analysis, measurements, and user-defined load profiles for static and dynamic load control. This evaluation board is the ideal tool for studying and designing SMPS circuits, optimizing circuit designs for optimal performance, and quickly implementing and testing design changes.

The DC2166A evaluation board incorporates a 3.3V or 5V microcontroller to achieve programmable operating conditions. The microcontroller can be used to provide power-management functions, background functions, and control functions. The microcontroller also provides control, monitoring, and signal conditioning capabilities. Furthermore, the microcontroller provides a variety of interfaces such as Pulse Width Modulation (PWM), Pulse Frequency Modulation (PFM), Serial Communication Interface (SCI), and Inter Integrated Circuit (I2C) interface.

The DC2166A evaluation board can be configured in the buck or boost mode for testing various traditional TOPSwitch devices including the TOP241, TOP246, and TOP243. For the boost mode application, the evaluation board uses a combination of field-effect transistors (MOSFETs) and integrated switches (IGBTs) to achieve high current drive capability. It can also be used in continuous conduction mode and can be easily configured to simulate under no-load and light-load conditions. In addition, the DC2166A evaluation board can also be used in paralleling applications by providing a master/slave control interface to enable synchronization between two or more evaluation boards.

In terms of operational safety, the DC2166A evaluation board provides thermal protection and overload protection through the use of temperature-sensing circuits and external power sensing coils. In addition, an output voltage transducer is also incorporated on the board to allow for monitoring of output voltage. To ensure proper safety, all components used on the evaluation board are carefully chosen and tested for compatibility, reliability, and performance.

The DC2166A Evaluation board also offers a comprehensive set of measurement choices. The board is equipped with an input, output voltage, current, power-factor, and output EMI measurement and filtering capabilities. In addition, the board offers protection against overvoltage and undervoltage, as well as input power-factor correction. Furthermore, the board includes two analog-to-digital converter (ADC) blocks which facilitate the use of a wide range of analog sensors and temperature measurements. Also, an analog output line is included for the connection to external devices.

Overall, the DC2166A Evaluation board is an extremely versatile and user-friendly instrument, providing an extensive range of SMPS testing and design capabilities. The board supports both traditional and emerging DC/DC and AC/DC solutions, which are becoming increasingly important as the industry moves towards the adoption of new technologies. With its user-friendly design, comprehensive measurement capabilities, and built-in safety features, the DC2166A Evaluation board is an invaluable tool for engineers and designers.
