Murata Power Solutions OKLP range of Power Block Non-Isolated DC-DC converters sit 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 11.1mm and has a typical efficiency rating of 94%. The maximum benefits are achieved when coupled with the ZMDI ZSPM1035 single-phase digital PWM IC controller family. OKLP-X/25-W12-C provides 70A/in2 @ 55°C with 200LFM airflow. The OKLP-X/25-W12-C has incorporated all of the power handling components required for a 25A PoL design. The maximum benefits are achieved when coupled with the ZMDI ZSPM1025 single-phase digital PWM IC controller family.
