60A “Power Block” provides power density to 481 W/cubic inch



Murata has announced the latest addition to the OKLP range of “Power Block” products from Murata Power Solutions. In addition to the 25A & 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.

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-X60-W12A-C provides a regulated 0.6-3.63 VDC output of up to 60A from a 7-13.2 VDC input and is suited for use in point-of-load (PoL) applications. Efficiency, rated at 12 Vin and 3.3 Vout, is typically 95% and with its compact dimensions of 25.4 x 12.7 x 12.2 mm, a power density of up to 481 Watts per cubic inch can be achieved.

The OKLP-X/60-W12A-C is ideally suited for powering FPGAs, ASICs, and microprocessors and providing I/O voltages in Intermediate Bus Architecture applications.
