The IRDC3847 Evaluation Board SMPS, a programmable, off-line DC/DC converter, provides the power-supply design engineer with fast, accurate, and cost-effective way to evaluate Infineon and third-party ICs. The board can generate an adjustable output voltage of 24V with up to 500W of total available output power capacity. The IRDC3847 Evaluation Board has a wide input voltage range of 90VAC to 277VAC. The board includes on-board EMI filtering, a seven-step PFC design, integrated EMI filter, protection circuitry, a control board interface, and on-board monitoring and control features.

The IRDC3847 Evaluation Board can be used in a variety of applications, including DC/DC and AC/DC switch-mode power supplies (SMPS) designs. The board can also be used to evaluate power factor correction (PFC) architectures, on-board loops for current-mode control, and other advanced features. The board also allows for the evaluation of third-party ICs such as Power Integrations\' SCALE-2 and ELTEK\'s SMPS controllers.

The working principle of the IRDC3847 Evaluation Board is straightforward. It uses an I(x) controller to regulate the output voltage by controlling the primary side of half-bridge MOSFET switch. Through its seven-step PFC design, it is able to provide a highly regulated and stable DC/DC converter with up to 500 W of output power. Furthermore, the board has a built-in protection circuit, which limits inrush currents during start-up and protects the converter from over-current, over-voltage, and over-temperature conditions. The board also provides an output control loop to increase the efficiency of the converter by using a low-power cycle skipping technique.

The IRDC3847 Evaluation Board is a versatile, off-line, programmable DC/DC converter that is ideal for evaluating Infineon and third-party ICs. It can be used in a variety of applications, ranging from DC/DC and AC/DC switch-mode power supplies (SMPS) designs to evaluation power factor correction (PFC) architectures.
