The NV890130PDR2GEVB, or Evaluated Board, is a powerful tool for DC/DC and AC/DC off-line SMPS applications. It is designed for evaluation purposes and is equipped with a wide range of features to help in the selection, evaluation, and design of complex DC/DC and AC/DC SMPS applications. This board does not work as a final product and is typically used as an intermediate product in order to better access the features and make design adjustments prior to final product design.

The NV890130PDR2GEVB Evaluated Board is based on the LTC8901, a highly integrated, digitally controlled, isolated AC/DC mid-voltage (300V to 540V) converter controller. The LTC8901 provides various features to design SMPS topologies in applications such as power supplies, motor drives, and other supplies in industrial and consumer-corners. The board has been equipped with up to 800W power density and is operable up to 100 kHz switching frequency, and is designed to demonstrate the unique features of the LTC8901 such as ECO mode, CSAMP mode, dynamic phase shedding, active share, and adjustable VCC, gate drive, and voltage reference. Furthermore, the board carries an isolated variable input voltage, loop compensation for maximum flexibility, and a highly efficient power stage.

In terms of working principle, the NV890130PDR2GEVB Evaluated Board is designed to provide a high power density and efficiency with precise voltage regulation and very adjustable behavior. It works with an analog input voltage sourced from the power supply connected to the board. This input voltage is then rectified and regulated by the LTC8901 to feed the various components on the board. The board receives a digital feedback signal from the output stage and the controller uses this feedback signal to control the output voltage. The output stage is driven by a PWM output signal from the controller. The output voltage is then monitored and controlled by the LTC8901.

The NV890130PDR2GEVB Evaluated Board is ideal for power supply design applications such as power supplies, motor drives, and other supplies used in industrial and consumer-corners. The board is a complete solution for evaluation and design purposes that can assist in evaluating and understanding the various features of the LCT8901. With the wide range of features and high power density capabilities, the NV890130PDR2GEVB board is a great choice for DC/DC and AC/DC off-line SMPS applications.
