Ce circuit fonctionne sur la gamme de tension d’entrée de 2,7 V à 4,8 V ce qui convient aux batteries à un élément Li-ion ou aux lignes de tension de niveau logique 3,3 V. Sa fréquence de commutation fixe de 2,2 MHz permet l’emploi de petits composants externes. Ceux-ci, associés au boîtier DFN de 2 x 2 mm à diode Schottky intégrée font que ce composant présente une solution simple, d’empreinte compacte, pour les applications de polarisation à faible niveau de bruit.
\nLe commutateur interne, à haut rendement, fonctionnant à la fréquence fixe de 2,2 MHz génère en sortie du régulateur LDO une tension de 15 V à très faible niveau d’ondulation et de bruit inférieur à 500 µV crête-à-crête. Son contrôle en mode courant assure une réponse rapide aux transitoires, sans avoir recours à une compensation externe complexe. Afin d’améliorer la fiabilité du système, ce circuit possède une protection contre les courts-circuits et une protection thermique ainsi que la fonction de déconnexion de la charge à l’arrêt.
\nProposées en boîtier DFN-8, de 2 x 2 mm, la version LT3048EDC-15 offre une température de jonction jusqu’à 125 °C et la version de classe de températures industrielles LT3048IDC-15 est garantie de -40 °C à +125 °C.<\/p>\n<\/p>\n
