Caractérisé à 600 V, ce circuit utilise une commande en mode courant moyen à hystérésis pour réguler le courant plus précisément. Il comprend un pilote de MOSFET côté bas associé à un régulateur interne de haute tension, ainsi qu’une mesure de courant côté haut. Le convertisseur s’avère compatible avec les variateurs électroniques PWM, permettant un contrôle du courant de 0 % à 100 %.<\/p>\n

“Dans le secteur à forte croissance de l’éclairage à DEL, il y a un besoin élevé de solutions électroniques de commande à bas coût pour délivrer une sortie à courant constant aux LED de puissance à forte luminosité. Le circuit LEDrivIR IRS2980 apporte aux applications de commande de LED non isolée des performances supérieures pour un coût système plus faible que celui des solutions alternatives,” explique Peter Green, responsable du groupe LED au sein de la division Produits d’économie d’énergie d’IR.<\/p>\n

Disponible en boîtier SO-8, ce composant bénéficie de la technologie de fabrication haute tension avancée qui s’appuie sur les dernières technologies de décalage de niveau et de terminaison de tension pour offrir une plus grande fiabilité et une protection contre le stress électrique supérieure, tout en incorporant d’autres fonctions et des améliorations supplémentaires.<\/p>\n
