L’ISL68300 peut directement piloter des MOSFET externes discrets, tandis que l’ISL68301 se couple aux \u00e9tages de puissance intelligents de Renesas ou aux \u00e9tages de puissance DrMOS pour cr\u00e9er une solution compl\u00e8te de r\u00e9gulateur de tension.<\/p>\n

Les contr\u00f4leurs num\u00e9riques ISL68300 et ISL68301 disposent d’un bus de partage de courant \u00e0 grande vitesse permettant de parall\u00e9liser jusqu\u2019\u00e0 huit contr\u00f4leurs dans une configuration de partage de courant \u00e0 8 phases de 240A et plus. Les deux contr\u00f4leurs impl\u00e9mentent la modulation de contr\u00f4le num\u00e9rique ChargeMode de Renesas, qui r\u00e9pond aux transitoires de charge en un seul cycle de commutation, et fournit une boucle de r\u00e9gulation intrins\u00e8quement stable sans n\u00e9cessiter de compensation externe. Cette architecture de modulation r\u00e9duit consid\u00e9rablement les besoins en condensateurs de sortie et minimise les fluctuations autour de Vout.<\/p>\n

 \u00ab L’\u00e9volutivit\u00e9 des contr\u00f4leurs num\u00e9riques \u00e0 sortie unique ISL68300 et ISL68301 fournit des performances de pointe et prend en charge un large \u00e9ventail de courants de charge \u00bb, a d\u00e9clar\u00e9 Mark Downing, vice-pr\u00e9sident de la division Core Power Solutions de Renesas Electronics Corporation. \u00ab Les nouveaux contr\u00f4leurs num\u00e9riques compl\u00e8tent nos contr\u00f4leurs multiphases num\u00e9riques prim\u00e9s \u00e0 double sortie, offrant aux clients tout ce dont ils ont besoin pour alimenter tous les rails de leurs syst\u00e8mes de nouvelle g\u00e9n\u00e9ration. \u00bb<\/p>\n

Les ing\u00e9nieurs peuvent utiliser l’interface graphique PowerNavigator avec les ISL68300 et ISL68301 pour simplifier l\u2019installation, le s\u00e9quen\u00e7age, la configuration et la surveillance de l’alimentation, y compris tous les param\u00e8tres de l’appareil et la t\u00e9l\u00e9m\u00e9trie. Les sch\u00e9mas complets de conception sont r\u00e9alis\u00e9s en quelques minutes, et l’interface graphique avec PMBus permet de contr\u00f4ler facilement l’ensemble de la conception et de modifier les caract\u00e9ristiques sans devoir retravailler ou souder les composants.
