The LM2736X EVAL/NOPB is a evaluation board designed by Texas Instruments that enables the testing of the LM2736X controller for the design of offline DC/DC and AC/DC switch mode power supplies (SMPS). The LM2736X EVAL/NOPB has multiple debugging features, including an adjustable buck regulator, a synchronous buck regulator and a flyback regulator, with the option to easily switch between them. This evaluation board can boost/buck up to 36V with thermal protection in both circuits. It is designed to provide greater operational flexibility and performance.

The LM2736X EVAL/NOPB is a high-performance, integrated solution that is suitable for a wide range of applications, from industrial, automotive power management, to consumer and computer power supplies. It has features such as adjustable soft-start and peak current limit. It offers a wide range of output voltage and current settings for both buck and boost regulator configurations. It also features an integrated single-switch flyback regulator for high-efficiency applications. The integrated MOSFETs are rated for 35V and have a maximum current ratings of 3A and 5A, respectively.

The LM2736X EVAL/NOPB operates with multiple input and output capacitors ranging from 2nF to 100nF, and its input voltage range is 4-36V while its output voltage ranges from 0.83-36V. The evaluation board also features a dual-control input signal which allows the user to monitor the input and output voltage and current values. Additionally, the LM2736X has integrated current sensing capabilities to monitor the current input and output. It also has thermal protection, as well as over-current, over-voltage and under-voltage protection features.

The LM2736X EVAL/NOPB’s working principle is two-fold. First, the power signal is fed into the buck regulator circuit, and the voltage is adjusted by the output control voltage signal. The voltage is then transferred to the booster circuit, where it is further adjusted by the boost control voltage signal. Finally, the regulated output is sent to the load.

The evaluation board also allows the user to adjust the voltage and current values directly from a microcontroller or a power management IC. Additionally, the LM2736X EVAL/NOPB can be configured to operate with either a single output or multiple outputs depending on the application. The evaluation board also comes with a graphical user interface to make debugging and evaluation of the power supply much easier.

In conclusion, the LM2736X EVAL/NOPB is a highly capable evaluation board that enables the development and evaluation of DC/DC and AC/DC switch mode power supplies in a wide variety of applications. It is feature-rich, highly configurable and comes with some powerful debugging features.
