Murata announces power block design

Murata has announced a line oF power blocks aimed to provide the power system architect with an alternative design approach for non- isolated DC/DC conversion. This concept, developed by Murata Power Solutions to meet the growing demand for increased power densities. According to the firm, the solution sits between a discrete point-of-load (PoL) design and that of a complete non-isolated PoL converter module. The power block is essentially a non-isolated buck converter without the PWM controller.

The power block design approach allows the power engineer to achieve the highest efficiency and maximum possible power and current density while maintaining a high performance system at a lower cost when compared to a complete module design approach, stated the company. Murata's power block provides a single component solution that incorporates all of the power handling components, fully tested and characterized for thermal and dynamic performance. The power block design approach is geared for power-hungry FPGAs, ASICs, computing and IBA architectures. Most analogue 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 product using this approach, the OKLP-X/25-W12-C, is a 25A rated module and is optimised for the ZMDI series of digital controllers that incorporate PMBus communications.

By combining the ZSPM1025 controller IC and the 25A Murata power block engineers can implement a full pre-configured 25A 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 up to four different output capacitor ranges without any additional design work.

The OKLP power block measures 12.7 x 17.02 x 10.7mm and has a typical efficiency rating of 93.5 per cent. Input voltage is around a nominal 12VDC and can accommodate the range of 7-13.2VDC.

Volume pricing is in the $7 range, with lead-times of 8-10 weeks. Sample quantities will be available from stock.
