DC/DC converter delivers up to 481W/cubic inch
Murata Power Solutions has announced the latest addition to the OKLP range of 'Power Block' products, the OKLP-X60-W12A-C 60A solution. Essentially a non-isolated buck converter without the PWM controller, this 'Power Block' concept sits between a discrete PoL design and that of a complete non-isolated buck converter module.
The OKLP-X/60-W12A-C provides a single package solution that incorporates all of the power handling components, fully tested and characterised 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 analogue or digital PWM controllers can be used with the 'Power Block'.
The OKLP-X60-W12A-C provides a regulated 0.6-3.63VDC output of up to 60A from a 7-13.2VDC input and is suited to use in PoL applications. Energy efficiency, rated at 12VIN and 3.3 VOUT, is typically 95% and, with its compact dimensions of 25.4x12.7x12.2mm, a power density of up to 481W/cubic inch. It is suited for powering FPGAs, ASICs, MPUs and providing I/O voltages in intermediate bus architecture applications.
Reference designs are available using Texas Instrument’s TPS40425 (a two-phase, stackable PMBUS synchronous buck controller).
