Power Block achieves high efficiency at lower cost

Measuring 25.4mm x 12.7mm x 11.1mm, the power block has a typical efficiency rating of 94%. The input voltage is a nominal 12VDC and can accommodate the range of 7VDC to 13.2VDC.

The design of the power block enables designers 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. The device provides a single package solution that incorporates all of the power handling components, fully tested and characterized for thermal and dynamic performance.

Designed for today’s 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 ZSPM1035 single-phase digital PWM IC controller family. The device coupled with the ZSPM1035 provides a ready, tested, and optimally preconfigured 35A point-of-load solution. Also available is a downloadable construction kit that includes step-by-step instructions and a software wizard. Further to this, ZMDI’s Pink Power Designer GUI allows fast module configuration that speeds time-to-market. The digital control loop provides ultra-fast transient response, steady-state performance, stability, and design flexibility. Up to four different output capacitor ranges can be supported by selecting the preconfigured ZMDI controller.

“We are excited to offer this unique Power Block architecture to power systems design engineers as it provides them with flexibility and options to improve power density, performance, and overall system costs,” commented Bill Smith, Director of Marketing, Board Mount Power, for Murata Power Solutions. “We see our OKLP Power Block series as a means to address the ever-growing requirements for increased power densities in networking applications.”
