Abstract
(EN)
A device and method for hybrid feedback control of a switch-capacitor multi-unit voltage regulator are presented. A multi-unit switched-capacitor (SC) core includes a plurality of SC converter units, each unit with a capacitor and a plurality of switches controllable by a plurality of switching signals. Power switch drivers provide a switching signal to each SC converter unit. A secondary proactive loop circuit includes a feedback control circuit configured to control one or more of the plurality of switches. A comparator is configured to compare the regulator output voltage with a reference voltage and provide a comparator trigger signal. Ripple reduction logic is configured to receive the comparator trigger signal and provide an SC unit allocation signal. A multiplexer is configured to receive a first clock signal, a second clock signal, and the SC unit allocation signal and provide a signal to the power switch drivers.

Dispositif et procédé pour commande à rétroaction hybride d'un régulateur de tension à unités multiples à condensateur de commutation. Un noyau de condensateur commuté (SC) à unités multiples comprend une pluralité d'unités de conversion de SC, chaque unité ayant un condensateur et une pluralité de commutateurs pouvant être commandés par une pluralité de signaux de commutation. Des pilotes de commutation de puissance apportent un signal de commutation à chaque unité de conversion de SC. Un circuit à boucle proactive secondaire comprend un circuit de commande à rétroaction conçu pour commander un ou plusieurs commutateurs de la pluralité de commutateurs. Un comparateur est conçu pour comparer la tension de sortie de régulateur à une tension de référence et apporter un signal de déclenchement de comparateur. Une logique de réduction d'ondulation est conçue pour recevoir le signal de déclenchement de comparateur et apporter un signal d'allocation d'unité SC. Un multiplexeur est conçu pour recevoir un premier signal d'horloge, un deuxième signal d'horloge et le signal d'allocation d'unité SC et apporter un signal aux pilotes de commutation de puissance.
