摘要： Disclosed herein is a circuit including first and second input circuits. The first input circuit is configured to receive first and second logic signals and to source current to first and second control nodes if at least one of the first and second logic signals is at a logic low. The second input circuit is configured to receive the first and second logic signals and to sink current from the first and second control nodes if at least one of the first and second logic signals is at a logic high. A first output circuit is configured to source current to an output node when current is sunk from the first control node. A second output circuit is configured to sink current from the output node when current is sourced to the second control node. A latch is coupled to the output node.

摘要： A switching converter includes a first electronic switch and a second electronic switch and respective drive circuits for switching on and switching off alternatively the first and second electronic switches. The drive circuits have a supply line for supplying to them a supply voltage. At least one of the drive circuits has, coupled to it, a capacitor for storing the supply voltage. An electronic-switching circuit is provided for selectively disconnecting the drive circuit from the supply line when the electronic switch driven thereby is switched off. In this mode, the drive circuit is supplied by the voltage stored on the capacitor.

摘要： First and second comparators receive input signals of opposed polarities and drive operation of a switch in response thereto. A first current generator supplies a first current to the switch which, in response to the control of the first and second comparators, applies the first current, alternatively, to a first node or a second node. A second current generator sinks a second current from the first node and a third current generator sinks a third current from the second node. A logic circuit has inputs coupled to the first node and the second node, respectively, receives respective switching signals having fast switching wavefronts and delayed switching wavefronts. The output of logic circuit is configured for switching between a first state and a second state with switching between the first state and the second state triggered by the fast switching wavefronts of the respective switching signals.

摘要： A battery charger operates in a current regulation mode and a voltage regulation mode. A value of the voltage on the battery being charged is sensed and compared against a target voltage value. The current regulation mode is active during charging while the sensed voltage is less than the target voltage value. When the sensed voltage reaches the target voltage value, the voltage regulation mode is enabled and the current regulation mode is inhibited.

摘要： A level-shifter circuit operates to shift an input signal referenced to a first set supply voltages to generate an output signal referenced to a second set of supply voltages. The output signal from the level-shifter circuit is latched by a latching circuit. A logic gate has a first input configured to receive the input signal, a second input configured to receive a feedback signal and an output coupled to a input of the level shifting circuit. A feedback circuit has a first input configured to receive the output signal, a second input configured to receive the input signal and an output configured to generate the feedback signal. The feedback circuit operates to sense an uncontrolled switching event of the output signal occurring in the absence of a switching of the input signal and apply, in response thereto, the feedback signal to cancel the uncontrolled switching event.
