La fréquence de découpage du A8601 peut être soit programmée soit synchronisée avec un signal d’horloge externe entre 350kHz et 2.25MHz pour minimiser les interférences avec les bandes radio AM et FM.
\nLes cinq tensions de sortie sont générées par 3 régulateurs linéaires et par 2 régulateurs à pompe de charge. Chaque tension de sortie peut être ajustée indépendamment. Les sorties sont mises sous et hors tension via une séquence
\npréprogrammée pour répondre aux exigences des panneaux LCD, ce qui simplifie le design.
\nCe composant est extrêmement robuste lors d’erreurs. Une protection contre les courts-circuits est présente sur chaque sortie ; le régulateur boost est protégé contre les sur-courants et les surtensions, une protection contre la déconnexion de l’entrée est assurée par la commande d’un MOSFET canal P externe. Le A8601 est disponible dans un boîtier eTSSOP 28 broches avec une semelle dissipatrice permettant un fonctionnement à des températures plus élevées.<\/p>\n
