摘要： A DC-DC converter has a control circuit for controlling a high-side power transistor and a low-side power transistor connected in series between supply terminals to which an input supply voltage is applied. The converter has a switching node at the interconnection of the power transistors for connection of an inductor to which a load is connected. The control circuit has a feedback loop that provides a pulse width modulated control signal, logic circuitry to which the pulse width modulated control signal is applied and gate drivers with inputs connected to outputs of the logic circuitry and outputs applying gate drive signals to the gates of the power transistors. A digital signal is obtained which is indicative of whether the converter switching node is at a potential above or below a zero reference at the time of the turn-off edge of the low-side gate drive signal. The turn-off edge of the low-side gate drive signal is advanced or delayed by a predetermined amount in response to the value of the digital signal.

摘要： An apparatus is provided that uses a first level shifter for performing a voltage shift of a low level input signal of a first voltage domain to a high level output signal of a second voltage domain. The first level shifter comprises a storing element in the second voltage domain, an input stage coupled to the storing element for providing a signal state to be stored in the storing element and a feedback loop from an output of the storing element to the input stage for controlling the input stage in response to a transition of a high level output signal of the storing element.
