L’IRS2580DS comprend un circuit de commande à convertisseur élévateur fonctionnant en mode fréquence à conduction critique et assurant la correction du facteur de puissance avec une très faible distorsion harmonique totale (THD). Ce circuit intègre également un étage de commande en demi-pont 600 V doté d’un rapport cyclique de 50 % et d’une fréquence variable, assurant la commande d’une sortie lampe en mode résonnance.
\nContrairement aux approches alternatives, le Combo8 IRS2580DS offre d’excellentes performances PFC, une grande précision et une THD réduite à travers une large gamme de charges et de tensions, le tout dans un seul boîtier 8 broches. En outre, comme deux de ses huit broches servent de contrôle primaire pour le ballast, il constitue une solution simple avec un nombre de composants réduit, ce qui accélère la conception de manière significative.
\nUn montage complet de protection est également inclus pour se prémunir de problèmes tels que l’interruption complète ou partielle de tension, les défauts de lampe ou encore la rupture de filament. L’IRS2580DS ne requiert que deux broches de contrôle primaire pour assurer toutes les fonctions nécessaires au ballast. Ces fonctions comprennent une entrée de conversion analogique tension-fréquence pour le préchauffage, l’allumage et le fonctionnement de la lampe et une broche de sortie PWM pour le contrôle des temps d’allumage et d’extinction durant chaque cycle de découpage du convertisseur élévateur PFC.<\/p>\n
