Abstract
A controller for a switching converter with a power switch includes a gate driver, a first transistor, and a regulator. The gate driver and provides a drive voltage to control the power switch based on a switch control signal. The first transistor is coupled between a first power supply node and a power supply terminal of the gate driver. A current sense signal representative of a current flowing through the power switch is provided to a floating node in response to the switch control signal being a first level, and the floating node is coupled to a reference ground in response to the switch control signal being a second level. A gate voltage of the first transistor is adjusted by the regulator coupled to the floating node based on a float reference voltage and a feedback voltage provided by a feedback stage.
