(FR) CONVERTISSEURS DE TENSION CC-CC DOTÉS DE DISPOSITIFS DE COMMANDE
Abstract
(EN)
A system (100) comprises a DC-to-DC voltage converter (102), the DC-to-DC voltage converter comprising: a high-side FET (104) comprising a gate, a source, and a drain; a node (124) coupled to the source of the high-side FET(l04); a low-side FET (106) comprising a gate, a source, and a drain coupled to the node (124); and a controller (110) coupled to the gate of the high-side FET (104) to switch on and off the high-side FET (104), and coupled to the gate of the low-side FET (106) to switch on and off the low-side FET (106), the controller configured to switch on the low- side FET (106) for a time interval before switching on the high-side FET (104) and to switch off the low-side FET (106) before switching on the high-side FET(l04).
