IRDC3651 is an evaluation board for DC/DC and AC/DC (off-line) switch mode power supplies. It is designed to evaluate the performance of high power density DC/DC and AC/DC converter designs. The board features two regulation paths, one for DC/DC and one for AC/DC, which are connected in parallel.

The input voltage capabilities range from 9V to 36V, with up to 7A continuous current for DC/DC and 5A peak current for AC/DC. The output voltages can be adjustable between 0.8V and 15V. The IRDC3651 is also capable of operating as an adjustable step-up, step-down, and isolated converter.

The IRDC3651 evaluation board utilizes a simplified power stage layout, combining the switching FETs into a single package. This makes it easy to build and characterize a range of topologies, such as buck, boost, and SEPIC. The board also features integrated current sensing and voltage measurements, along with control signals for start-up sequence and output regulation.

The IRDC3651 power supply is based on an industry-standard design topology that includes an integrated soft-start controller and a high-side floating-gate driver. By using the soft-start controller, the IRDC3651 can provide a regulated output while limiting both inrush and input current. The floating-gate driver allows the user to adjust the switching frequency and duty cycle of the FETs, allowing for more accuracy and control of the output.

The IRDC3651 evaluation board is designed to provide users with a complete set of tools to evaluate various design solutions as quickly and accurately as possible. This board supports a wide range of topologies, and it is also capable of operating and characterizing power supplies at higher voltage and higher current levels. In addition, the evaluation board includes built-in protection features such as input current limiting and thermal protection.

Overall, the IRDC3651 evaluation board is an excellent tool for evaluating high power density DC/DC and AC/DC converter designs. It supports a wide range of topologies, from low power designs to high current designs, and it features integrated current sensing and voltage measurements. Furthermore, the board features an integrated soft-start controller and floating-gate driver, allowing the user to adjust the switching frequency and duty cycle of the FETs for greater accuracy and control.
