Abstract

Convertisseur continu-continu à pompe de charge adapté à convertir une tension d’entrée (VBAT) en une tension de sortie (VCP) plus élevée, comportant : - un oscillateur (4) ; - un circuit à pompe de charge doubleur de tension (3) ; - un étage secondaire (5) du circuit à pompe de charge ; - un interrupteur d’activation (6) adapté à commander l’étage secondaire (5) en tripleur de tension ; - un comparateur (7) adapté à mesurer la différence de tension entre la tension d’entrée (VBAT) et la tension de sortie (VCP) et à piloter l’interrupteur d’activation (6) pour commander l’état activé de l’étage secondaire (5) lorsque ladite différence de tension est inférieure à un seuil de tension prédéterminé. Figure pour l’abrégé : Fig. 2
