Abstract:
Exemplary embodiments are related to switching power converters. A switching power converter may comprise a plurality of control unit configured for average current mode control, wherein each control unit of the plurality comprises a dedicated proportional control unit. The switching power converter may further comprise an integrator coupled to each control unit of the plurality of control unit and configured to convey a signal to each control unit.
Abstract:
A method for unbalancing a tri-level switching regulator uses hysteretic control when switching across multiple states of the tri-level switching regulator. The method includes determining a battery voltage and an output voltage of the tri-level switching regulator. The method also includes dynamically adjusting at least one of a first hysteretic window of a first hysteretic comparator associated with a second switching state of the tri-level switching regulator and a second hysteretic window of a second hysteretic comparator associated with a first switching state of the tri-level switching regulator based on the battery voltage and the output voltage.
Abstract:
Certain aspects of the present disclosure are directed to a regulator. The regulator generally includes a source follower circuit and a low-voltage assist circuit. The low-voltage assist circuit generally includes a first transistor having a gate coupled to an output node of the source follower circuit, a voltage comparison circuit having a first input coupled to a source of the first transistor and a second input coupled to a control input node of the source follower circuit, and a second transistor having a gate coupled to an output of the voltage comparison circuit and a drain coupled to the output node of the source follower circuit.
