 Le LT8642S r\u00e9duit fortement les \u00e9missions d\u2019EMI (interf\u00e9rences \u00e9lectromagn\u00e9tiques) gr\u00e2ce \u00e0 des fronts de commutation contr\u00f4l\u00e9s et une implantation interne avec l\u2019emploi de colonnettes de cuivre \u00e0 la place de plots et un plan de masse int\u00e9gral. Cette am\u00e9lioration des performances relatives aux EMI ne d\u00e9pend pas de la configuration de la carte PCB, ce qui simplifie la conception et r\u00e9duit le risque m\u00eame en utilisant deux couches de circuit imprim\u00e9. Le LT8642S satisfait aux limites cr\u00eates des EMI de la norme CISPR 25 de Classe 5 de l\u2019automobile, avec une fr\u00e9quence de commutation de 2MHz, sur toute la plage de la charge. La modulation de fr\u00e9quence par \u00e9talement de spectre est disponible pour abaisser davantage les niveaux d\u2019EMI.<\/p>\n

Le LT8642SEV est encapsul\u00e9 en un bo\u00eetier LQFN, 4mm x 4mm. Une version pour temp\u00e9ratures industrielles, le LT8642SIV, est test\u00e9e et garantie pour fonctionner avec une temp\u00e9rature de jonction de \u2013 40\u00b0C \u00e0 125\u00b0C. Les deux versions sont disponibles en stock.<\/p>\n
