Abstract

L'invention concerne un circuit (30) de détection d'une surcharge dans une charge alimentée par une alimentation à découpage, comprenant : un premier comparateur (25) d'une première tension fonction de la tension d'alimentation de la charge par rapport à un premier seuil (VFB), fournissant un signal (CT) de régulation à un générateur (6) d'impulsions de commande de l'alimentation à découpage ; un deuxième comparateur (31) d'une deuxième tension par rapport à un deuxième seuil (VOVL), fournissant un signal (OVL) indicateur de la présence d'une surcharge ; et des moyens (C33, 34, 35, M35) pour asservir ladite deuxième tension sur un troisième seuil (VINI) inférieur au deuxième et supérieur au premier, et pour désactiver le deuxième comparateur tant que cet asservissement est maintenu.
