35A POL solutions designed for servers, storage units

ZMDI and Murata Power Solutions have released a true-digital 35A point-of-load solution that has applications in servers, storage units, and FPGA designs. ZMDI's ZSPM1035 single-phase digital PWM controller family ICs for non-isolated DC/DC supplies was combined with Murata Power Solutions' single-phase 35A surface-mount power block to provide smart digital power solutions. ZMDI's software enables the user to customise solutions for optional digital communications via PMBus, output voltage range, and output load. The digital control loop and compensators are preconfigured in the new ZSPM1035 family devices. A downloadable complete construction kit is available, including a graphical user interface, layout guidelines, and step-by-step instructions. It is ready to be immediately implemented in the application design.

The new ZSPM1035 family, together with the existing ZSPM1025 family, provides a range of ready-to-use smart digital power solutions up to 35A. ZMDI plans to extend this further with dual-phase, true-digital POL controllers for Murata Power Solutions' dual-phase surface-mount power blocks with higher output current capabilities in early 2014.

"With the addition of the ZSPM1035 digital PWM controller family ICs for the 35A Murata Power Block, we are extending our successful application-ready 25A POL solutions up to 35A. Our customers especially value the proven technology of ZMDI and Murata at higher currents," said Andrew Smith, Product Marketing Manager at ZMDI. "To help our customers quickly add the customised POL solution in their end-application, we provide complete construction kits containing documentation, layout and tools."

The ZSPM1035A, ZSPM1035C, and ZSPM1035D are in full production. Parts and ZSPM8035, ZSPM8735, and ZSPM8835 evaluation kits are available at Mouser Electronics.
