Les ing\u00e9nieurs d’\u00e9tude peuvent \u00e9galement g\u00e9n\u00e9rer des courants sur rail plus \u00e9lev\u00e9s en branchant jusqu’\u00e0 4 unit\u00e9s en parall\u00e8le pour permettre la fourniture d’un courant allant jusqu’\u00e0 320 A comme un rail d\u2019alimentation unique.
\nQuelque soit la configuration, la plage de tension d’entr\u00e9e s\u2019\u00e9tend de 7,5 V \u00e0 14 V et la tension de sortie est toujours r\u00e9glable entre 0,6 V et 5,2 V, ce qui signifie qu\u2019un large \u00e9ventail d\u2019applications et de dispositifs \u00e0 semi-conducteurs peut \u00eatre pris en charge.<\/p>\n

Des fonctions de commande, aussi bien analogiques que num\u00e9riques, permettent au module d’\u00eatre soit command\u00e9 avec des r\u00e9sistances, soit command\u00e9 et surveill\u00e9 \u00e0 l\u2019aide de l\u2019interface num\u00e9rique PMBus standard du march\u00e9. Des applications telles que le traitement de graphiques, de donn\u00e9es ou de vid\u00e9o, \u00e0 l\u2019aide de dispositifs \u00e0 puissance \u00e9lev\u00e9e, tels que les processeurs pour serveurs, les FPGA, les supercalculateurs, les \u00e9quipements de r\u00e9seau, de stockage et de t\u00e9l\u00e9communications, peuvent b\u00e9n\u00e9ficier de la densit\u00e9 de courant, du rendement et de la flexibilit\u00e9 de contr\u00f4le de ce convertisseur DC-DC num\u00e9rique.<\/p>\n

Pour simplifier l’\u00e9valuation, la configuration et le suivi, un logiciel graphique sur PC avec un kit d\u2019\u00e9valuation est propos\u00e9. Deux onglets intuitifs donnent aux d\u00e9veloppeurs la possibilit\u00e9 de saisir les r\u00e9glages n\u00e9cessaires pour les diff\u00e9rents convertisseurs et de suivre l’\u00e9tat et les param\u00e8tres. La carte de d\u00e9monstration est pourvue de deux modules LGA80D permettant aux ing\u00e9nieurs d’\u00e9tude de tester le fonctionnement \u00e0 modules empil\u00e9s ou \u00e0 voie ind\u00e9pendante.<\/p>\n

L’ajout d\u2019un centim\u00e8tre carr\u00e9 est susceptible de faire une diff\u00e9rence consid\u00e9rable, avec l\u2019espace lib\u00e9r\u00e9 pouvant \u00eatre affect\u00e9 \u00e0 des fonctions de traitement suppl\u00e9mentaires.\u00a0\u00bb<\/p>\n
