Ce r\u00e9gulateur fonctionne \u00e0 partir d\u2019une gamme de la tension d\u2019entr\u00e9e comprise entre 3,4 V et 60 V et procure une tension de sortie n\u00e9gative r\u00e9glable dans la gamme de 0 \u00e0 -28 V, tout en g\u00e9n\u00e9rant un courant continu de sortie jusqu\u2019\u00e0 4 A.  Ses larges gammes de tensions d\u2019entr\u00e9e et de sortie sont bien appropri\u00e9es \u00e0 une grande vari\u00e9t\u00e9 d\u2019applications de tests, de mesures et de dispositifs industriels.<\/p>\n

La conception unique du circuit inclut une source de courant interne de pr\u00e9cision de 50 \u00b5A sur la broche ISET qui lui permet de g\u00e9n\u00e9rer des tensions de sortie aussi basses que -28 V en utilisant une seule r\u00e9sistance de programmation externe. De plus, il pr\u00e9sente une pr\u00e9cision de la tension de sortie de \u00b10,8%. La fr\u00e9quence de commutation est programmable par l\u2019utilisateur de 300 kHz \u00e0 3 MHz, autorisant l’emploi de condensateurs et inductances de petite taille et de faible co\u00fbt. Avec un petit bo\u00eetier QFN ou TSSOP \u00e0 28 broches, il pr\u00e9sente ainsi une empreinte tr\u00e8s compacte.<\/p>\n

Ce composant int\u00e8gre des transistors commutateurs \u00e0 r\u00e9sistances RDS(0N) <\/sub>de seulement 110 mohms et 50 mohms pour atteindre des rendements aussi \u00e9lev\u00e9s que 92%. Le fonctionnement en Burst Mode assure un fort rendement aux faibles charges, requ\u00e9rant un courant de repos de seulement 440 \u00b5A. Pour les applications sensibles au bruit, le r\u00e9gulateur peut \u00eatre configur\u00e9 pour fonctionner en mode continu forc\u00e9 pr\u00e9sentant une tr\u00e8s faible ondulation en sortie. Son horloge r\u00e9f\u00e9renc\u00e9e \u00e0 la masse et la broche PGOOD \u00e9liminent le besoin des mises \u00e0 niveau.
\nLes caract\u00e9ristiques compl\u00e9mentaires incluent un gestionnaire de la tension r\u00e9gul\u00e9e, la programmation de la compensation des chutes de tension dans les c\u00e2bles, la possibilit\u00e9 d\u2019une synchronisation externe et une protection thermique.<\/p>\n

Encapsul\u00e9 en bo\u00eetier QFN-28 (suffixe UFD) de 4 x 5mm, et TSSOP-28 (suffixe FE) \u00e0 performances thermiques renforc\u00e9es, ce composant est propos\u00e9 en classe E et en classe industrielle indice I garantie pour fonctionner sur la gamme de la temp\u00e9rature de jonction de -40 \u00b0C \u00e0 +125 \u00b0C.<\/p>\n
