Encapsul\u00e9 dans un bo\u00eetier miniature LGA  l\u00e9ger et ultra fin, de seulement 6,25 x 6,25 x 1,82 mm, ce \u00b5Module peut \u00eatre soud\u00e9 sur l\u2019envers de la carte PCB o\u00f9 il occupe une surface de seulement 0,5 cm2<\/sup> (double face) ou 1 cm2<\/sup> (simple face) avec une r\u00e9sistance et trois condensateurs.<\/p>\n

Pouvant fournir 3 A sur la broche VDDQ et \u00b13 A sur la broche VTT, deux modules en parall\u00e8le peuvent g\u00e9n\u00e9rer jusqu\u2019\u00e0 6 A par ligne de tension pour des barrettes de m\u00e9moires plus importantes. Pour une intensit\u00e9 sup\u00e9rieure \u00e0 6 A en sortie VDDQ, ce composant peut \u00eatre associ\u00e9 au LTM4630 pour g\u00e9n\u00e9rer de 18 A \u00e0 36 A sur la sortie VDDQ, pour de tr\u00e8s grands r\u00e9seaux de SRAM. Si la tension VDDQ est d\u00e9j\u00e0 disponible, le module peut \u00eatre configur\u00e9 pour alimenter une seule sortie VTT biphase, jusqu\u2019\u00e0 6 A.<\/p>\n

Ce r\u00e9gulateur peut fonctionner sur une alimentation d\u2019entr\u00e9e basse de 3,3 V, ainsi que sur des alimentations d\u2019entr\u00e9e standard de 5 V et 12 V (jusqu\u2019\u00e0 15 V). Chacune des deux tensions de sortie VDDQ et VTT est dans la gamme de 0,6 V \u00e0 2,5 V. La troisi\u00e8me sortie est une sortie tamponn\u00e9e de 10 mA, \u00e0 bas niveau de bruit, pour la tension VTTR de la SRAM. (VTTR= VDDQ\/2)<\/p>\n

Les applications comprennent les syst\u00e8mes PCIe, ceux en lien avec le cloud, les syst\u00e8mes RAID, le traitement vid\u00e9o et les r\u00e9seaux utilisant des RAM de type DDR \/ DDR-II \/ DDR-III \/ DDR4 \/ QDR \/ QDR-II \/ QDR-II+ et QDR4.<\/p>\n

Con\u00e7u pour fonctionner de -40 \u00b0C \u00e0 +125 \u00b0C, ce module int\u00e8gre dans son bo\u00eetier LGA ultra fin, un r\u00e9gulateur DC\/DC \u00e0 trois sorties, compos\u00e9 de deux circuits, et des commutateurs de puissance, auquel s\u2019ajoutent des inductances et composants externes.<\/p>\n
