Murata announced the latest addition to the OKLP range of "Power Block" products from Murata Power Solutions. In addition to the recently introduced 25 A, Murata now offers the OKLP-X/35-W12-C, a 35 A Power Block solution. This Power Block concept sits between a discrete Point-of-Load (PoL) design and that of a complete non-isolated buck converter module. The Power Block is essentially a non-isolated buck converter without the PWM controller. The OKLP-X/35-W12-C power block measures 25.4 x 12.7 x 11.1 mm and has a typical efficiency rating of 94%. Input voltage is a nominal 12 VDC and can accommodate the range of 7 to 13.2 VDC.
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. Murata's Power Block provides a single package solution that incorporates all of the power handling components, fully tested and characterized for thermal and dynamic performance. The Power Block design approach is ideal 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 combination of ZMDI's ZSPM1035 and the 35A Murata Power Block provides a ready, tested, and optimally preconfigured 35A point-of-load solution. Designers have access to a full downloadable construction kit that includes step-by-step instructions and a software wizard. 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.
