Abstract
A shoot-through prevention circuit is used in a power conversion circuit that uses a passive level-shifter to drive a P-type transistor in a switching network. The shoot-through prevention circuit is coupled between a controller output that provides a driving signal to control the P-type transistor and the passive level-shifter coupled to a control terminal of the P-type transistor. The shoot-through prevention circuit couples the controller output to the passive level-shifter when the driving signal has a first logic level associated with turning on the P-type transistor and isolates the controller output from the passive level-shifter when the driving signal has a second logic level associated with turning off the P-type transistor.
