November 2005[Cover Feature] Turning Hot Ideas Into Cool Designs
Thanks to growing component counts, falling board space, and increasing current requirements, effective thermal management has become one of the key challenges facing designers of distributed power architectures in applications ranging from telecommunications base stations to industrial control systems. In particular, a key goal for the designer is to ensure high-efficiency power conversion while achieving a balanced temperature across the PCB. The advent of intermediate bus...
October 26, 2004[Direct Feature] Small Is Cool
Significant increases in the power density of multiphase voltage regulator module (VRM) circuits have been enabled by the use of source-mounted power MOSFET devices. Increases in current density have been enabled by two factors. Firstly, package parasitic impedances have been reduced, and secondly, the thermal resistance between the power device junction and the external ambient has been dramatically cut. Exploiting the advantages of source-mounted packages depends...
