Title (EN) CURRENT MEASURMENTS IN SWITCHING REGULATORS
(FR) MESURES DE COURANT DANS DES RÉGULATEURS DE COMMUTATION
Abstract:
(EN) Features and advantages of the present disclosure include a switching regulator and current measurement circuit. In one embodiment, a switching transistor in the switching regulator has a first voltage on a first terminal and a switching voltage on a second terminal. A current measurement circuit has first and second input terminals. A first switch couples the second terminal of the switching transistor to the first terminal of the current measurement circuit when the switching transistor is on, where the second input terminal of the current measurement circuit is coupled to the first terminal of the switching transistor and measurement(s) may be taken. When the switching transistor is off, the first and second input terminals of the current measurement circuit are coupled together, and measurements emulate zero current through the switching transistor.
(FR) Les caractéristiques et avantages de la présente invention comprennent un régulateur de commutation et un circuit de mesure de courant. Selon un mode de réalisation, un transistor de commutation dans le régulateur de commutation a une première tension sur une première borne et une tension de commutation sur une seconde borne. Un circuit de mesure de courant comprend des première et seconde bornes d'entrée. Un premier commutateur couple la seconde borne du transistor de commutation à la première borne du circuit de mesure de courant lorsque le transistor de commutation est activé, où la seconde borne d'entrée du circuit de mesure de courant est couplée à la première borne du transistor de commutation et une(des) mesure(s) peu(ven)t être prise(s). Lorsque le transistor de commutation est désactivé, les première et seconde bornes d'entrée du circuit de mesure de courant sont couplées ensemble, et les mesures émulent un courant nul à travers le transistor de commutation.
