Ce convertisseur peut être configuré en mode élévateur, SEPIC, Flyback ou inverseur. Sa fréquence de commutation est programmable entre 100 kHz et 500 kHz, ce qui donne aux concepteurs la possibilité de réduire la taille des composants externes. Le fonctionnement en Burst Mode réduit le courant de repos à seulement 6 µA et maintient l’ondulation de la tension de sortie inférieure à 20 mV crête-à-crête. La combinaison d’un boîtier MSOP-16E haute tension et de petits composants externes autorise une empreinte très compacte et réduit le coût de la réalisation.
\nLe commutateur interne 0,5 A présente des rendements élevés allant jusqu’à 90%. Une seule résistance dans la boucle de régulation fixe la tension de sortie, qu’elle soit positive ou négative, ce qui minimise le nombre de composants externes. La broche SYNC\/MODE du composant assure la synchronisation à une horloge externe ou peut être utilisée pour effectuer un choix entre le fonctionnement en Burst Mode, pour un faible courant de repos IQ, et celui à densité variable d’impulsions, pour un niveau de bruit le plus bas possible. Les autres caractéristiques comprennent un arrêt en cas de sous-tension UVLO, un démarrage progressif interne, le repliement de fréquence et une protection par arrêt thermique.
\nLe LT8331EMSE est encapsulé en un boîtier MSOP- 16E pour forte tension. Une version LT8331IMSE de classe de température industrielle de -40 °C à +125 °C est également proposée.<\/p>\n<\/p>\n
