Abstract

L'invention concerne un convertisseur abaisseur de tension, comprenant un mode de réserve et un mode actif, pour une mémoire comprenant les composants suivants : un noeud de charge (68) conçu pour recevoir une charge ; un premier transistor (54) comprenant une première grille, ce premier transistor étant conçu pour fournir un courant de charge à la mémoire ; un premier commutateur (58) couplé au noeud de charge et à la première grille, ce premier commutateur étant conçu pour appliquer la charge du noeud de charge à la première grille pendant la transition entre le mode de réserve et le mode actif ; un second transistor (66) couplé à la première grille, ce second transistor étant conçu pour polariser le premier transistor à un état inactif pendant le mode de réserve ; un second commutateur (64) couplé au premier transistor et au second transistor, ce second commutateur étant conçu pour appliquer, au niveau du second transistor, une différence de tension à la première grille pendant le mode de réserve.
