Abstract:
1. A driving circuit for controlling operation of a switch, comprising: a first level shifter including a path along which a pulse-on current flows in response to an on-control signal and a path along which a pulse-off current flows in response to an off-control signal; a second level shifter including a path along which an on-control current flows in response to the on-control signal and a path along which an off-control current flows in response to the off-control signal; and a gate driver turning on or off the switch, wherein the gate driver turns on the switch in response to the pulse-on current, maintains the turned-on switch in the turn-on state in response to the on-control current, turns off the switch in response to the pulse-off current, and maintains the turned-off switch in the turn-off state in response to the off-control current.
