The NCP1601AGEVB application field and working principle is dedicated to providing users with a comprehensive solution for power management applications. It is a versatile system that consists of a development board, application specific integrated circuit (ASIC) controller, and a range of friendly development tools. The NCP1601AGEVB enables users to easily evaluate Texas Instruments’ fixed frequency, constant frequency PWM control solutions with a wide range of applications. Specifically, it is designed to accelerate development and performance evaluation of DC/DC converter architectures for systems such as servers, game consoles, automotive, telecom, point-of-load converters, and more.

The NCP1601AGEVB consists of two circuit boards: a development board and a target board. The development board is powered by a USB port, while the target board is powered by a power supply. The development board incorporates a Texas Instruments NCP1601 PWM controller device set to an application-specific solution, while the target board is a fixed-frequency or constant frequency PWM control circuit board. This board offers several features including programmable output voltage, output current sensing, soft start, programmable frequency (700 kHz to 170 kHz), and variable deadband. The outputs can be monitored or controlled with the help of system command line interface (CLI) and USB PC software. The controller can either be used to set the output voltage directly or the output voltage can be programmed via the PC software in the range of 0.6 V to 2.6 V with an accuracy of 0.1 V. The GUI software also provides the ability to control the output frequency and other configuration settings.

The PWM control circuit can be configured either for fixed frequency operation or constant frequency operation. In the fixed frequency mode, the system is capable of maintaining stable regulation by deriving the switching frequency directly from the control voltage. In the constant frequency operation, the system switches independently of the control voltage, enabling better accuracy and flexibility. Also, the system can be set in the auto sequencing mode which will enable it to sequence multiple devices in a predetermined sequence.

In order to help designers evaluate the performance of their circuits, the NCP1601AGEVB is supplied with a suite of development tools including bench-top power supply, test leads, simulation modeling tools, macro development environment, graphical user interface software (GUI), interface adapter board, and programming jig. With the development tools, users can measure the output current, voltage, ripple, and on-state efficiency, making it easy to evaluate the system and board architecture.

For added functionality and convenience, the NCP1601AGEVB also includes an on-board micro-USB connector for connection to a PC (the controller cannot be programmed or debugged via the micro-USB port). The on-board micro-USB connector allows users to access the development environment and program the system configuration as well as the board settings.

In conclusion, the NCP1601AGEVB is a versatile evaluation and demonstration board that provides users with a complete solution for power management applications. It offers users a wide range of features and development tools to help evaluate and refine their designs quickly and efficiently. With the NCP1601AGEVB, designers can more easily move from concept to implementation and ensure that their product is optimally designed without compromising on performance.
