Supportant la large gamme de tensions d\u2019entr\u00e9e de 18 V \u00e0 560 V, ce r\u00e9gulateur flyback utilise un commutateur de puissance int\u00e9gr\u00e9 de 0,3 A\/ 630 V pour fournir jusqu\u2019\u00e0 15 W en sortie, une puissance appropri\u00e9e aux v\u00e9hicules \u00e9lectriques et batteries d\u2019accumulateurs, aussi bien qu\u2019\u00e0 des applications hors ligne, automobiles, industrielles et m\u00e9dicales.<\/p>\n

Le circuit fonctionne en mode de conduction critique (boundary mode), quasi r\u00e9sonnant, qui consiste en un contr\u00f4le en mode courant, \u00e0 d\u00e9coupage et \u00e0 fr\u00e9quence variable, aboutissant \u00e0 une r\u00e9gulation de la charge et de la tension de ligne meilleure que \u00b1 1%. Ce mode permet l\u2019emploi d\u2019un transformateur plus petit que ceux employ\u00e9s dans les conceptions \u00e0 mode conduction continue \u00e9quivalentes. Plusieurs transformateurs standard, mentionn\u00e9s dans la fiche de caract\u00e9ristiques, peuvent \u00eatre utilis\u00e9s dans de nombreuses applications.
\nLe haut degr\u00e9 d\u2019int\u00e9gration et l\u2019emploi du fonctionnement en Burst Mode \u00e0 faible niveau d\u2019ondulation, conduisent \u00e0 un produit d\u2019utilisation simple, avec peu de composants, et de haut rendement pour les alimentations isol\u00e9es.<\/p>\n

Les caract\u00e9ristiques additionnelles comprennent une protection contre les courts-circuits, un courant de repos, \u00e0 vide, de 70 \u00b5A, une tension de validation pr\u00e9cise et une tension d\u2019arr\u00eat avec hyst\u00e9r\u00e9sis en cas de sous-tension, ainsi qu\u2019une compensation de temp\u00e9rature par diode en sortie.<\/p>\n

Ce composant est propos\u00e9 en bo\u00eetier TSSOP-20 avec suppression de quatre broches pour un espacement pour les tensions \u00e9lev\u00e9es. Les versions de classes industrielle et \u00e0 gamme de temp\u00e9rature \u00e9tendue fonctionnent avec une temp\u00e9rature de jonction de \u2013 40 \u00b0C \u00e0 +125 \u00b0C, et celle de classe automobile, de -40 \u00b0C \u00e0 150 \u00b0C.<\/p>\n
