US 2020/0007035 A1 · DC-TO-DC VOLTAGE CONVERTERS WITH CONTROLLERS TO SWITCH ON A LOW-SIDE FET FOR A TIME INTERVAL BEFORE SWITCHING ON A HIGH-SIDE FET

Abstract

A system comprises a DC-to-DC voltage converter, the DC-to-DC voltage converter comprising: a high-side FET comprising a gate, a source, and a drain; a node coupled to the source of the high-side FET; a low-side FET comprising a gate, a source, and a drain coupled to the node; and a controller coupled to the gate of the high-side FET to switch on and off the high-side FET, and coupled to the gate of the low-side FET to switch on and off the low-side FET, the controller configured to switch on the low-side FET for a time interval before switching on the high-side FET and to switch off the low-side FET before switching on the high-side FET.
