L’UCC28250 est le premier contrôleur PWM en demi-pont ou pont complet du marché, possédant la capacité de maintenir une tension de sortie en rampe monotone sous des conditions de charge pré-polarisées, en éliminant le recours à un circuit externe. Il peut réaliser un contrôle primaire ou secondaire et fournit jusqu’à 95% de rendement et une grande densité de puissance dans les applications CC\/CC isolées à haute tension d’entrée, telles que les modules d’alimentation utilisés dans les stations de base de téléphone cellulaire ou les systèmes d’alimentation industriels.
\nTI présente également le tout nouveau UCC28950, offrant deux sorties PWM supplémentaires pour des contrôles en pont intégral à décalage de phase jusqu’à 600W et atteint plus de 90% de rendement. Ce contrôleur avancé est doté d’un contrôle à redresseur synchrone et commute à zéro de tension adaptatif dans une large gamme de tensions d’entrée et de sortie pour réduire la perte de découpage, ce qui augmente le rendement de 20% par rapport aux meilleurs appareils du marché. L’UCC28950 améliore les performances d’alimentation dans les architectures à grande densité de puissance pour les solutions de contrôle moteur CC industrielles et dans les télécommunications.
