Abstract

An integrated switching mode power supply (10) has a follower device (59) providing a supply voltage (VBOOT) to a node (70) of the power supply. A driver circuit operates in response to an input signal (VCONTROL) and has an output (40) for providing a drive signal (VDRIVE) that bootstraps the node to a potential greater than the supply voltage.
