Abstract
A switching voltage converter in half bridge topology includes a control circuit for achieving a constant locking time for two power switches to switch between a TOP position and BOT position. The TOP switch is realized by one or more parallel-switched n-channel transistors and the BOT switch is realized by one or more parallel-switched p-channel transistors. Both of the power switches are controlled by a gate driver. The reference potential of the gate driver is at the potential of the output signal U of the half bridge. The driver is controlled by a switching-signal producing unit at the same reference potential as the driver , whereby unit and driver can be directly connected to each other.
