I. XDPP1100-Q024 Product Overview

The XDPP1100-Q024 is a highly integrated, programmable digital power controller from Infineon’s XDP™ series, optimized for isolated DC-DC power supply applications. Housed in a compact 24-pin VQFN package measuring just 4 mm × 4 mm, this device is one of the smallest digital power controllers in the industry.

The XDPP1100-Q024 is designed for a wide range of DC-DC power supply applications and supports various isolated and non-isolated topologies. Its unique architecture incorporates numerous optimized power management modules that effectively enhance the performance of isolated DC-DC converters, reduce the number of external components, and significantly lower the firmware development workload. The device also provides precise telemetry capabilities and a PMBus 1.3 interface to support system communication, advanced power conversion, and monitoring.

Through the single-chip integration of a high-performance analog front end (AFE), a state-machine-based digital control loop, and a microcontroller, the XDPP1100-Q024 provides a highly integrated, programmable, and extremely fast time-to-market solution for modern high-end power systems.
