The basic working principle of the 1789205X1 is to produce regulated DC power from an AC input. By implementing the concepts of pulse width modulation (PWM), the board is able to convert AC to DC power with high efficiency. The board has two separate channels that can be used to monitor AC and DC circuits independently. Each channel features an onboard voltage regulator, current sensor, and voltage measurement circuit. The current controller on the 1789205X1 is designed to control the current rise and fall times. The onboard overvoltage protection circuit ensures safe operation of the board in the event of an overvoltage condition.

The 1789205X1 evaluation board is a great tool for testing DC/DC and AC/DC (off-line) SMPS, particularly in applications that require precise voltage and current control. This provides the user with a simple and cost-effective way to evaluate the performance of their circuit without having to design and build their own. Additionally, the board is equipped with sophisticated monitoring and protection features, allowing for safe and reliable operation in even the most extreme operating conditions.
