Analog Devices shrinks high frequency DC-DC regulators The first of a range of high-frequency 6MHz DC-DC regulators, the ADP2121 buck regulator from Analog Devices is available in a 1.3mm x 0.9mm wafer level chip scale package (WLCSP) with a razor-thin height of 0.6mm. The device requires two small capacitors and one small inductor, resulting in a 35% reduction in PCB area compared with current 3MHz buck regulators. The ADP2121 is said to be suited to portable applications where board...
Active ORing family halves space
At this month’s electronica in Munich, Picor (www.picorpower.com), a subsidiary of Vicor, launched the Cool-ORing family of full function active ORing and discrete active controllers for redundant power architectures in high-availability systems. The family reduces power dissipation, according to the company, by up to x10 compared to conventional diode ORing solutions. This means that there is no need for unnecessary thermal management overhead in a form factor that has been reduced...
