MPRD48NH480M250A00 can be classified as an evaluation board from DC/DC and AC/DC (Off-Line) SMPS. It is a power switch board using the GaNMFET technology, developed by Murata Electronics, based on the GaN transistors discovered by transphorm. This power switch board is designed specifically for high power and high efficiency switching applications, like power supplies, and is suitable for industrial and consumer power systems.

The MPRD48NH480M250A00 board includes one of two types of evaluation boards. The first type is an adjustable board which is ideal for evaluation of the GaN transistors. This board uses a 48V input, along with an adjustable voltage output. The output voltage can be set from 1.5V to 48V using a potentiometer. The exterior measurements of this evaluation board are 51 x 51 mm. The second type is a standard board which provides fixed voltage outputs of 1.5V, 12V, 24V and 48V.

So what is the working principle of the MPRD48NH480M250A00 evaluation board? The main goal of the evaluation board is to evaluate the capacity of the transistors to switch power on and off with extremely low losses at high frequencies and high current levels. This is thanks to theunique structured of the transistors which enable them to switch power more efficiently compared to traditional switch-mode power supplies. The board consists of a synchronous full bridge stage and it operates by using the “pulse-width modulated” (PWM) switching technique. This technique generates a periodical square wave of the switching node voltage, which is then compared to the “zero intermediate current” control signal. This ensures that the power losses are kept low and the efficiency is maximized.

The MPRD48NH480M250A00 evaluation board can be used in a variety of applications. This includes AC/DC and DC/DC power supplies, AC/AC solid state relays, motor drives, LED lighting systems, home and office automation systems and many more.The evaluation board offers a variety of features that makes it ideal for these applications. It features a low input voltage range of 10V to 48V, adjustable output voltage range of 1.5V to 48V, low voltage drop, low-EMI operation, high efficiency (up to 95%) with full load and overcurrent/overvoltage protection. Furthermore, the board is compliant with the UL-60950-1, IEC-60950-1, EN 60950-1 and ECE R10 standards.

In summary, the MPRd48NH480M250A00 evaluation board can be classified as an evaluation board from DC/DC and AC/DC (Off-Line) SMPS. It uses the GaN transistor technology, which enables high power and efficiency switching applications and can be used for power supplies, AC/AC solid state relays, LED lighting systems and more.The board is suitable for industrial and consumer power systems and offers low voltage drop, low-EMI operation, high efficiency and many more features.
