Abstract

Interface d'alimentation USB-PD La présente description concerne une interface d'alimentation comprenant : un convertisseur (CONV) fournissant une première tension DC (Vsrc) ; une résistance (R) entre le convertisseur (CONV) et une borne (312) de sortie fournissant une deuxième tension DC (Vbus) ; un premier circuit (CIRC2) fournissant un deuxième signal (MOD) représentatif d'un écart entre la deuxième tension (Vbus) et un seuil de tension lorsqu'un premier signal (EN) est dans un premier état, et à une valeur par défaut sinon ; un deuxième circuit (AMP) fournissant un troisième signal (Isens) représentatif du courant (I) dans la résistance (R) multipliée par un gain du troisième circuit, et modifiant le gain à partir du deuxième signal (MOD) ; et un troisième circuit (CIRC1) fournissant un signal de commande (cmd) du convertisseur (CONV) à partir au moins du troisième signal (Isens).
