Its four monolithic, high efficiency buck regulators support Intel’s mobile CPU P-State and C-State energy saving operating modes. The output voltages are independently controllable via I2C, and each output can be independently started and shut down. Designers can choose from power saving pulse-skipping mode or Burst Mode<span class="emoticon" data-url="https://community.element14.com/cfs-file/__key/system/emoji/00ae.svg" title="Registered">&#x00ae;</span> operation, or select low noise LDO mode. The space-saving LTC3562 is available in a 3mm × 3mm QFN package and requires few external components.</p><p style="margin:0;padding:0px;">&nbsp;</p><p style="margin:0;"><a href="http://www.linear.com/pc/downloadDocument.do?id=26347" rel="nofollow ugc noopener" target="_blank"><img alt="smaller-pdf-icon.jpg" class="jive-image" src="http://www.element-14.com/community/servlet/JiveServlet/downloadImage/2716/smaller-pdf-icon.jpg" /></a></p><div style="clear:both;"></div> <div style="font-size: 90%;">Tags: sp:linear_technology_corporation, in:medical</div>
