IRDCIP2021C-1 is an integrated off-line AC/DC and DC/DC switch mode power supply (SMPS) evaluation board. It is designed to provide comprehensive evaluation of an off-line SMPS topology. The board is used for the evaluation of on-board integrated controllers, either pre-programmed as well as with the help of on-board reprogrammable microcontroller for an online application.

The IRDCIP2021C-1 is suitable for a wide range of applications, from industrial to consumer electronic products. It offers high performance, low cost, and an easy solution for developing robust AC/DC and DC/DC switching power supply applications. The board includes a number of features that make it the perfect choice for prototyping SMPS products.

The working principle of IRDCIP2021C-1 includes various power supply stages and controller components that are necessary to generate the output voltage. It consists of five major stages, namely, input, output, feedback, drive, and protection. In the input stage, the AC-DC converter is used to rectify the AC input and convert it into a usable DC supply. This is then used to power up the integrated controller, which controls the switching frequency, current and voltage of the output.

The output stage consists of an inductor, transformer, and power semiconductors such as MOSFETs, IGBTs, and rectifiers to transform and regulate the DC output voltage. In the feedback stage, an optical coupler or a voltage divider is used to measure the output voltage of the system. The feedback signal is sent back to the integrated controller in order to enable closed loop control and regulation of the output voltage.

The drive stage consists of a power stage and a gate driver. The power stage uses a set of pulse-width modulated (PWM) signals to control the switching of the power semiconductors while the gate driver is used to drive the power stage. Last but not least, the protection stage provides a variety of overvoltage, undervoltage, short-circuit, and over-current protection circuits to protect the system against overloads..

In conclusion, IRDCIP2021C-1 is an ideal solution for developing robust and cost-effective AC/DC and DC/DC switching power supply applications. It comes equipped with an integrated controller, advanced power stage, drive, and protection circuits, along with other useful features, that allow for quick and easy evaluation of performance. On-board reprogrammable microcontroller further enables modification of configuration parameters for better evaluation results.
