Abstract:
1. A split high side driver circuit comprising: a boost node, a phase node, a voltage input node, a buck node, and a high side input node; a first driver stage having an input coupled to the high side input node, an output, a first power terminal coupled to the boost node, and a second power terminal coupled to the phase node; a second driver stage having an input coupled to the high side input node through a delay circuit, an output, a first power terminal coupled to the boost node, and a second power terminal coupled to the phase node; a first transistor having a first power terminal coupled to the voltage input node, a second power terminal coupled to the buck node, and a control terminal coupled to the output of the first driver stage; a second transistor having a first power terminal coupled to the voltage input node, a second power terminal coupled to the buck node, and a control terminal coupled to the output of the second driver stage; and a switch coupled between the phase node and the buck node.
