The NN30312A-EVB-R2 is an evaluation board from ON Semiconductor ideal for evaluating the features of the NN30312A SMPS. It showcases the application field of the NN30312A SMPS, as well as its working principle. This evaluation board is best suited for DC/DC or AC/DC (off-line) SMPS, hence this article will focus on both these areas.

As a DC/DC or AC/DC (off-line) SMPS, the NN30312A-EVB-R2 is a highly effective and reliable choice. It has the capability to provide a wide range of power conversion in a single unit. In addition, it is an ideal solution for applications requiring high efficiency, small size, and high reliability. The NN30312A-EVB-R2 has a wide input voltage range of 10V to 600V, making it suitable for use in a variety of applications including industrial, automotive, and consumer applications. The board also features a current-mode PWM control system, which ensures stable and efficient output even in cases of high input voltage, as well as a Power Factor Correction (PFC) stage, to ensure high power efficiency.

The working principle of the NN30312A-EVB-R2 is based on the use of primary-side PWM control. This allows the NN30312A-EVB-R2 to operate with a low current drain on the output stage, while also ensuring high power conversion efficiency. The PWM control system allows the evaluation board to regulate the output voltage in the same way that a linear supply would, while consuming only a fraction of the current. The NN30312A-EVB-R2 also features a low-start-up current feature, which ensures that the system starts up smoothly without any potential damage due to high in-rush currents.

In addition to its DC/DC or AC/DC SMPS application field, the NN30312A-EVB-R2 board can also be used to evaluate the features of the NN30312A SMPS. It is equipped with several on-board test points for making accurate measurements. Furthermore, it is provided with a DIP switch, which allows the user to adjust the output voltage, and also to enable/disable certain features. The evaluation board also features several on-board LEDs, which help to indicate the status of the system.

The NN30312A-EVB-R2 board is a highly reliable and efficient DC/DC or AC/DC (off-line) SMPS solution. It provides a wide range of input voltage range, and its PWM control system is designed to ensure stable and efficient operation. The board also features several on-board test points and indicators, which help the user to monitor the system. Furthermore, the board has a low start-up current feature, to ensure safe start-up and operation.
