Ce contrôleur peut être configuré pour fonctionner en flyback ou en conduction\/élévation critique avec PFC. Il embarque également un bloc d’optimisation de la distorsion harmonique totale (THD) réduisant les harmoniques de courant. De plus, il présente une immunité élevée au bruit, ce qui simplifie la conception et abaisse le coût du système.
\nCe circuit offre également un courant de démarrage basse consommation inférieur à 50µA, un courant de fonctionnement de 2,5 mA, un courant de commande de +800mA\/-600mA ainsi qu’une protection en surintensité et en surtension statique et dynamique. Le faible temps de mise en conduction (on time) minimum rend possible la correction de facteur de puissance sur une large gamme d’entrée, pour un fonctionnement universel.
\nDisponible en boîtier SO-8, ce composant est garanti sans plomb et conforme RoHS.<\/p>\n
