Alors que les dispositifs concurrents sont capables de transformer un tension de 16 V en 3.3 V, ces nouveaux produits ON Semiconductor peuvent convertir du 18V en entrée, en 3.3V en sortie, et même descendre à 2.5V à partir d’une entrée 16V, tout en maintenant une fréquence de commutation constante de 2 MHz. Ces composants peuvent fonctionner sur une gamme de tension allant de 4.5 V jusqu’à 36V, et encaisser des tensions de rupture de charge jusqu’à 40V (45V pour les versions 890x3x), ce qui les rend bien adaptés aux conditions sévères des systèmes "start-stop" et des démarrages à froid. Les NCV890100, NCV890101, NCV890130 et NCV890131 fournissent 1.2A maximum de courant de sortie, tandis que les NCV890200, NCV890201 et NCV890231 peuvent fournir un courant de sortie jusqu’à 2A.<\/p>\n
