Ce convertisseur a été développé autour d’un système sur puce (SoC) multiprocesseur, un circuit de gestion de l’alimentation numérique de Powervation. Des algorithmes brevetés ont été développés afin d’optimiser les performances dans les applications les plus exigeantes et d’aider l’ingénieur à tenir des délais de développement serrés.
\nLe module délivre un maximum de 25 A à 1,2 Vcc, à une température maximum de +70 °C avec un flux d’air de 200 LFM. Il fonctionne sur la plage étendue de tensions d’entrée allant de 6,5 à 14 Vcc. La tension de sortie Vout peut être réglée entre 0,69 V et 3,63 V à l’aide d’une seule résistance extérieure. Il présente une réponse en charge dynamique ultra rapide qui compense automatiquement les diverses conditions externes, y compris les charges capacitives, les niveaux de courant, la température, la tension d’entrée et le réglage de Vout.
\nL’utilisation du contrôleur buck synchrone de Powervation permet d’obtenir une des meilleures performances du marché dans la catégorie des POL 25 A. Le concept fait appel aux techniques de contrôle de la chaleur brevetées propriétaires, au magnétisme spécifique et à plusieurs fonctions de protection de circuit.
\nCe système est particulièrement bien adapté pour les ingénieurs à la recherche d’une sortie stable dans toutes les conditions, d’un rendement optimum et d’une tension de sortie programmable.
\n"Nous sommes heureux de pouvoir proposer ce convertisseur PoL 25A aux concepteurs de systèmes d’alimentation. Ils ont ainsi à leur disposition la flexibilité et les options requises pour améliorer la densité de puissance, les performances et le coût global du système" déclare Bill Smith, responsable du marketing Puissance montable sur carte chez Murata Power Solutions “Nos convertisseurs OKLF 25A ont été imaginés pour répondre aux besoins toujours croissants en matière d’alimentation des ASIC et FPGA de prochaine génération et de densités de puissance plus importantes dans les applications réseau."<\/p>\n
