XDP™ integrated digital power controller with PMBus for isolated DC-DC power applications
The XDPP1100-Q040 is a highly-integrated and programmable XDP™ digital power supply controller. This device offers advanced power control solutions for a wide variety of DC-DC power applications and supports various isolated and non-isolated topologies.
The unique architecture of the XDPP1100-Q040 includes many optimized power-processing blocks to enhance the performance of isolated DC-DC converters, reduce external components, and minimize firmware development efforts. This controller also provides accurate telemetry and a Power Management Bus (PMBus 1.3) interface for system communication, advanced power conversion, and monitoring. Integrated current-sensing capability and compact chip size can greatly reduce the solution size by eliminating many external components, while supporting up to two fully independent voltage loops.
A combination of high-performance AFE, state-machine-based digital control loop, and a microcontroller integrated in a single chip makes the XDPP1100-Q040 a highly integrated, programmable, and fastest time-to-market technology for modern high-end power systems. Hence, it perfectly qualifies for being employed in telecom infrastructures, 48V server motherboards, datacenters, and industrial 4.0 applications. This product is designed to meet power quality and latency challenges and to provide the most optimal solution for high-end power systems.
