35-A DC-DC converter module powers FPGA and embedded applications
The 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 35 A Murata Power Block provides a ready, tested, and optimally preconfigured 35 A 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.
Mouser Electronics as an authorized distributor for both ZMDI and Murata Power Solutions will be able to provide the ZMDI controllers, GUI interface, Murata’s OKLP and Evaluation Boards.
