Abstract

Circuit d'alimentation (1) d'une charge électrique (LD) servant à l'amenée d'une tension de sortie (VOUT) en fonction d'un signal de commande de charge (PWM1) en forme d'impulsion. Le circuit d'alimentation (1) selon l'invention comprend un convertisseur continu-continu (DCC) connecté pour générer la tension de sortie (VOUT) à partir d'une tension d'entrée (VIN) sur la base d'un signal de commutation (S_SW1, S_SW2) en forme d'impulsion, et un chemin de retour pour générer une tension de retour (VFB) sur la base de la tension de sortie (VOUT). Un comparateur (DA) est aménagé pour générer, sur la base d'une comparaison de la tension de retour (VFB) avec une tension comparative (VREF), une tension de compensation (VCOMP) sur une sortie (VO) du comparateur (DA). Le circuit d'alimentation (1) selon l'invention comprend en outre une unité de génération de signaux (PG) pour générer le signal de commutation (S_SW1, S_SW2) sur la base de la tension de compensation (VCOMP), et une unité tampon (PU1) qui est conçue pour amortir la tension de compensation (VCOMP) durant une phase de charge du signal de commande de charge (PWM1) et pour transmettre cette tension de compensation amortie à une connexion (TC1, TR1) couplée à la sortie (VO) du comparateur pendant une phase de charge suivante du signal de commande de charge (PWM1).
