IRDCIP1001-A is an evaluation board of DC/DC and AC/DC (off-line) SMPS. It enables users to accurately assess the performance of high-performance switching power converter designs. For SMPS designed with Infineon’s high reliability, low-power, high-efficiency (IRFDC) chips, the IRDCIP1001-A provides a fully documented, robust platform to create innovative products with minimized time-to-market constraints.

IRDCIP1001-A offers an IP (intellectual property) core specifically designed for 10A application field. This core is designed to accurately assess the performance of Infineon’s IRFDC power management ICs, reduce design complexity, and simplify requirements in terms of operating conditions. The core can be used in various modes, including step-down ratios (adjustable holds) and fixed-frequency switching operations with various duty cycles.

The IRDCIP1001-A evaluation board also features a number of user-friendly features. A user-friendly graphical user interface allows users to control parameters, such as output voltages, switching frequency, load current, etc., for easy testing. The board also includes a built-in power measurement facility to measure consumption and efficiency. Moreover, the IRDCIP1001-A offers a wide input voltage range of 6V to 36V and is compliant with the EN55022 Class B immunity standards.

The board is based on a fixed-frequency, current-mode topology. This topology provides excellent line/load regulation accuracy with a very high switching frequency of up to 400kHz. It also provides excellent noise and EMI characteristics, which makes it well-suited for cost-sensitive applications. The IRDCIP1001-A also includes the capability of using pulse-width-modulated (PWM) burst mode operation during light load and power saving operations.

The working principle of the IRDCIP1001-A evaluation board is based on the low-power, high-efficiency Infineon\'s IRFDC power management ICs. The board is designed with an on-chip synchronous rectifier and driver, which drives the output bridge MOSFETs at the selected frequency. The control IC also includes active current limit, over-temperature protection, thermal shutdown protection, over-voltage protection and under-voltage protection. The output stage of the board is driven by the IC\'s integrated PWM generator. It provides PWM drive signals to the output power stage bridge MOSFETs. The IC\'s smart voltage regulator loop (VRL) also provides constant output voltage regulation even during dynamic load conditions and very small load conditions.

In conclusion, the IRDCIP1001-A evaluation board is a highly reliable, low-power, high-efficiency DC/DC and AC/DC (off-line) SMPS platform. With its on-chip synchronous rectifier and driver, PWM drive signals, and VRL voltage regulation, the board is ideal for cost-sensitive applications and provides excellent noise and EMI characteristics. It also enables users to accurately assess the performance of high-performance switching power converters.
