The MIC4520 <http://www.micrel.com/_PDF/MIC4520.pdf>/MIC4521 <http://www.micrel.com/_PDF/MIC4521.pdf> utilizes Micrel's high performance FETZilla⢠DMOS technology to achieve high efficiency (over 90 percent peak). Micrel's IntelliMOS power MOSFETs have been optimized for low gate capacitance to enable fast switching performance (up to 1.2MHz) for minimal switching losses while their low on-resistance reduces conduction losses.
"Board space and heat dissipation constitute major challenges in cloud computing systems, so designers need high efficiency and compact DC-DC solutions. Micrel's IntelliMOS power stage solution meets these challenges and enables designers to reduce their solution size by operating at higher switching frequency while maintaining very high efficiency," statedBrian Hedayati, vice president of marketing for high performance linear and power solutions at Micrel. "Micrel's IntelliMOS solutions provide accurate monitoring and protection when used with Micrel'sMIC21000 <http://www.micrel.com/_Autologin/requestMIC21000.php> digital controller. Designers can build a complete point of load solution with full monitoring, dynamic scaling of output voltage and fault protection."
