The NBM6123E60E12A7T0R is an evaluation board that is used for designing and testing DC/DC & AC/DC (Off-Line) SMPS circuits. It is capable of providing a regulated output voltage with its built-in control system. This board is designed with an isolated case, which protects sensitive components from overvoltage or other EMI interferences.

NBM6123E60E12A7T0R\'s power input range is from 90V AC to 264V AC and its output voltage range is from 0.45V to 60V DC. The board uses the EMI filter coupled with a soft starter for its protection and provides over-voltage, over-temperature, over-load, and under-load protection. It also supports various control schemes like PFC, PWM, and hyst properties.

The NBM6123E60E12A7T0R uses MOSFETs at the power stage for switching the load current. The board is also built with an optocoupler for isolating the control input and output currents. It also utilizes a feedback voltage sensing capability to monitor the load current and control the output voltage.

The working principle of the NBM6123E60E12A7T0R is based on a conventional buck topology. In this topology, the output current is regulated by controlling the voltage of an oscillator. This is done by connecting the oscillator to a frequency compensation circuit. Depending on the current feedback, the voltage of the oscillator is varied and the switching frequency of the MOSFETs is adjusted accordingly. This mechanism ensures superior load regulation and improved efficiency.

The NBM6123E60E12A7T0R evaluation board can be used to design and test various types of DC/DC & AC/DC (Off-Line) SMPS circuits. It is a cost-effective way to verify the performance and efficiency of a circuit before implementation in a real-world application. This board is also compliant with the FCC, UL, CE, and CCC safety standards.
