R\u00e9duire le volume de l’alimentation tout en optimisant ses performances thermiques<\/u><\/p>\n

La taille de la solution et ses performances thermiques sont des consid\u00e9rations essentielles dans la conception d’alimentations destin\u00e9es aux circuits FGPA modernes. Gr\u00e2ce \u00e0 sa capacit\u00e9 d’empilement unique, le convertisseur abaisseur TPS546D24A r\u00e9pond \u00e0 ces deux probl\u00e9matiques. Il est dot\u00e9 d’une interface PMBus offrant un r\u00e9seau de compensation interne s\u00e9lectionnable, permettant ainsi aux concepteurs de circuits d’\u00e9liminer jusqu’\u00e0 six composants de compensation externes et de r\u00e9duire la taille globale de l’alimentation de puissance de plus de 10 % (ou 130 mm2) par rapport aux contr\u00f4leurs multiphas\u00e9s classiques sur les circuits ASIC ou les FGPA \u00e0 haute intensit\u00e9. De surcro\u00eet, le TPS546D24A affiche une faible r\u00e9sistance thermique (8,1\u00b0C par watt) et une temp\u00e9rature de fonctionnement inf\u00e9rieure de 13 \u00b0C \u00e0 celle des convertisseurs CC-CC concurrents ; il renforce ainsi la fiabilit\u00e9 des syst\u00e8mes \u00e9lectroniques op\u00e9rant dans des environnements chauds et difficiles, tels que les unit\u00e9s de base de bande ou les \u00e9quipements d’essai automatis\u00e9s.<\/p>\n
