Power blocks for power-hungry FPGAs, ASICS, and IBAs introduced by Murata Power

MANSFIELD, Mass., 14 Nov. 2013. Murata Power Solutions in Mansfield, Mass., is introducing the first in a series of power blocks designed as alternatives for non- isolated DC-DC conversion for today’s power-hungry field-programmable gate arrays (FPGAs), application-specific integrated circuits (ASICs), computing, and information-based architectures (IBAs).

This concept sits between a discrete point-of-load (PoL) design and that of a complete non-isolated PoL converter module. The power block is a non-isolated buck converter without the PWM controller.

The power block one-component design provides power handling components, tested and characterized for thermal and dynamic performance.

Most analog or digital PWM controllers can be used with the power block; however, the maximum benefits are achieved when coupled with ZMDI’s ZSPM1025 single phase digital PWM IC controller family.

The first power block product is the OKLP-X/25-W12-C, is a 25-amp module optimized for the ZMDI series of digital controllers that incorporate PMBus communications.

By combining the ZSPM1025 controller IC and the 25-amp Murata power block, engineers can implement a pre-configured 25-amp point-of-load solution. This includes a downloadable construction kit with step-by-step instruction and a software wizard, and is an FPGA designer-friendly solution. This implementation supports to four different output capacitor ranges without any additional design work.

The OKLP power block measures 12.7-by-17.02-by-10.7-millimeter and has a typical efficiency rating of 93.5 percent. Input voltage is around a nominal 12 volts DC and can accommodate the range of 7 to 13.2 volts DC.
