Murata has announced the latest addition to the OKLP range of “Power Block” products from Murata Power Solutions. In addition to the 25A and 35A, Murata now offers the OKLP-X/60-W12A-C, a 60A 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. It provides a single package solution that incorporates all of the power handling components, fully tested and characterized for thermal and dynamic performance.
Recommended: Digital Isolators Provide up to 2W of Isolated Power
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. Most analog or digital pwm controllers can be used with the Power Block. Reference designs are available using Texas Instrument’s TPS40425 (2-Phase, Stackable PMBUS Synchronous Buck Controller).

The OKLP-X/60-W12A-C is suited for powering FPGAs, ASICs, and microprocessors and providing I/O voltages in intermediate bus architecture applications. Lead-time is from stock to 16 weeks; pricing in OEM quantities $10.20.
