Ce sont des alimentations compl\u00e8tes r\u00e9gul\u00e9es et abaiss\u00e9es (step-down) qui d\u00e9livrent un courant de sortie de 25A, 33A, dual 25A, 50A et 70A, tout en fonctionnant sur des rails d’alimentation standard de 12V ou 5V. La famille RAA210xxx fournit une conversion de point de charge (POL) pour les composants avanc\u00e9s tels que les FPGA, les DSP, les ASIC et la m\u00e9moire utilis\u00e9s dans les serveurs, le stockage, les \u00e9quipements de t\u00e9l\u00e9communication et de r\u00e9seau. Chaque r\u00e9f\u00e9rence int\u00e8gre un contr\u00f4leur PWM, des MOSFET, une inductance et des passifs dans un module encapsul\u00e9 HDA (High Density Array) optimis\u00e9 thermiquement. Tout ce qui est n\u00e9cessaire pour compl\u00e9ter l\u2019alimentation est constitu\u00e9 de condensateurs (bulk) en entr\u00e9e et en sortie.<\/p>\n

\nLe RAA210xxx est une famille de modules d\u2019alimentation num\u00e9riques simplifi\u00e9s et abordables compatibles (broche \u00e0 broche) avec la s\u00e9rie compl\u00e8te de fonctions num\u00e9riques ISL827xM de Renesas. Les modules d’alimentation num\u00e9riques simples RAA210xxx offrent une programmation num\u00e9rique en fonctionnement, afin de prendre en charge des modifications de configuration avec un sous-ensemble de commandes PMBus, ainsi que la t\u00e9l\u00e9m\u00e9trie compl\u00e8te et la surveillance du syst\u00e8me. Si un contr\u00f4le num\u00e9rique plus avanc\u00e9 est requis ult\u00e9rieurement, la mise \u00e0 niveau vers les modules ISL827xM compatibles en terme de brochage permettra le partage de courant avec plusieurs modules connect\u00e9s en parall\u00e8le, l’acc\u00e8s \u00e0 toutes les commandes PMBus \u00e0 l’aide de l’outil PowerNavigator\u2122 et d\u2019avoir une m\u00e9moire non volatile pour le stockage de configuration.<\/p>\n

\u00ab Nos modules d’alimentation num\u00e9riques simples acc\u00e9l\u00e8rent la mise sur le march\u00e9 de produits par des \u00e9quipes de conception qui souhaitent une solution d’alimentation num\u00e9rique plus facile \u00e0 utiliser et \u00e0 moindre co\u00fbt \u00bb, a d\u00e9clar\u00e9 Philip Chesley, vice-pr\u00e9sident de la division commerciale industrielle \u00ab Analog and Power \u00bb de Renesas Electronics Corporation. \u00ab Les produits d\u2019alimentation num\u00e9riques simples RAA210xxx confortent le leadership de Renesas dans les domaines de la densit\u00e9 de puissance, de l\u2019efficacit\u00e9 \u00e9lev\u00e9e et des performances transitoires rapides, afin de r\u00e9pondre aux fortes exigences des syst\u00e8mes multi-rail en terme de point de charge. \u00bb<\/p>\n

Le bo\u00eetier exclusif HDA de la famille RAA210xxx offre des performances \u00e9lectriques et thermiques in\u00e9gal\u00e9es \u00e0 pleine charge gr\u00e2ce \u00e0 un substrat monocouche conducteur qui transf\u00e8re efficacement la chaleur du module vers la carte syst\u00e8me et la dissipe sans n\u00e9cessiter de flux d\u2019air ou de dissipateur thermique. Les cartes \u00e0 espace restreint tirent pleinement parti de la densit\u00e9 de puissance \u00e9lev\u00e9e du bo\u00eetier HDA, impossible \u00e0 atteindre avec des composants discrets. Les modules d\u2019alimentation num\u00e9riques simples RAA210xxx exploitent l\u2019architecture de contr\u00f4le ChargeMode brevet\u00e9e par Renesas, qui offre une efficacit\u00e9 maximale de 96% et sup\u00e9rieure \u00e0 90% dans la plupart des conditions. Ils fournissent \u00e9galement une r\u00e9ponse transitoire rapide \u00e0 un seul cycle en courant de charge de sortie, ce qui r\u00e9duit la capacit\u00e9 du condensateur et r\u00e9duit ainsi les co\u00fbts et la taille de la carte.<\/p>\n
