Evaluation boards (DC/DC & AC/DC (Off-Line) SMPS) are designed to measure and test the performance of electronic devices for use in different applications. The NV890201MWTXGEVB evaluation board is a low cost solution for the high-efficiency DC/DC converter designed by STMicroelectronics.

The NV890201MWTXGEVB evaluation board is suitable for automotive, consumer, industrial, and other applications that demand very high efficiency for low power losses. It utilizes an innovative single-stage power factor corrector design combining high voltage (>50V) MOSFET technology and step-down inductors, while its design achieves a high efficiency of up to 96% in all operating conditions.

The NV890201MWTXGEVB evaluation board is compatible with a variety of packages, such as SO-8 and DPAK-8. The components of the board are integrated with high-voltage MOSFETs, Schottky diodes, P-channel MOSFETs, and flyback diodes. The components are also compatible with a variety of protection and control functions.

The NV890201MWTXGEVB evaluation board is designed to evaluate the performance of the NV890201MWTXGEVB DC-DC converter in applications requiring high efficiency, such as in automotive, industrial, and consumer applications. It includes all the necessary components to quickly demonstrate the features of the converter, such as power factor correction (PFC) capability, reverse-mode operation, voltage and current sensing, over-current and thermal-protection features.

The evaluation board has a wide input voltage range, from 8V to 36V. It also has a low quiescent current and very low output ripple voltage. The board also provides two isolated output voltages, a high-side logic voltage, and a regulated lower voltage rail. The evaluation board also includes protection against over-voltage and under-voltage as well as over-temperature protection.

The working principle of the NV890201MWTXGEVB evaluation board is based on the integration of a high-voltage switching MOSFET, a Schottky diode, an integrated flyback diode, a P-channel MOSFET, and high-voltage inductors. The high voltage MOSFET is used as a switch that can be turned on and off in order to control the output voltage. This allows for the changeover between the switching states and thus reduces the total power consumption of the system. The Schottky diode functions as a rectifier to convert the alternating current (AC) input into a direct current (DC) output. The integrated flyback diode is used to ensure that any high voltage spikes are suppressed. The P-channel MOSFET is used to shut off the supply to the load and stop the conversion of DC into AC. The high voltage inductors are used to store the energy from the DC-DC converter when the MOSFET is turned off.

The NV890201MWTXGEVB evaluation board is an easy-to-use device that offers a convenient and flexible way to evaluate the performance of the STMicroelectronics NV890201MWTXGEVB DC-DC converter. The design of the board incorporates features such as power factor correction, reverse-mode operation, voltage and current sensing and protection features that make it ideal for automotive, industrial, and consumer applications that require high efficiency and low power losses.
