Abstract: A switching converter with reduced dead-time and without reverse-recovery is disclosed. The switching converter includes a first power switch coupled to a second power switch, a mode detector and a controller. The mode detector is adapted to detect a mode of operation of the first power switch and the second power switch, and to identify a first period during which the first power switch is turned on and operates in a linear mode while the second power switch is turned off. The controller is adapted to bias the second power switch with a predetermined voltage during the first period to turn on the second power switch during a second period. In the second period the first power switch is operating in a saturation mode.

Abstract: A gate drive circuit arranged to receive an input signal and provide an output signal to drive a gate of a transistor is presented. The gate drive circuit comprises a filter circuit arranged to attenuate a frequency band from the input signal when deriving the output signal from the input signal. The filter circuit contains programmable resistive elements, comprising: a first programmable resistive element arranged to adjust a low frequency gain and bandwidth of the gate drive circuit; a second programmable resistive element arranged to adjust a high frequency gain of the gate drive circuit; and a pair of programmable resistive elements arranged to adjust a driving gain of the gate drive circuit. A method of receiving an input signal and deriving an output signal from an input signal is also presented. The step of deriving an output signal comprises attenuating a frequency band from the input signal.

Abstract: A multi-level buck converter is provided with multiple control loops to regulate the output voltage across a wide duty cycle range while also regulating the flying capacitor voltage. The regulated flying capacitor voltage is exploited to drive the switch transistors that float with respect to ground.
