摘要： A multi-phase non-inverting buck boost voltage converter has a plurality of buck boost voltage regulators. Each regulator is associated with a separate phase for generating a regulated output voltage responsive to an input voltage. A plurality of current sensors are each associated with one of the plurality of buck boost voltage regulators for monitoring an input current to the associated buck boost voltage regulator and generating a current sense signal for the associated phase. A plurality of buck boost mode control circuitries are each associated with one of the buck boost regulator for controlling an associated buck boost voltage regulator using peak current mode control in a buck mode of operation and valley current mode control in boost mode of operation responsive to a common error voltage and the associated current sense signal. The plurality of buck boost mode control circuitries provides current balancing between the phases. A voltage error circuit generates the error voltage responsive to the regulated output voltage

摘要： A current sense amplifier includes a high-side current sense amplifier and a low-side current sense amplifier. The high-side current sense amplifier provides a current sense voltage signal for use with a voltage regulator and generates the current sense voltage signal responsive to a first current sensed through a high-side switching transistor in a first mode when the high-side switching transistor is turned on and the low-side switching transistor is turned off. The high-side current sense amplifier generates the current sense voltage signal responsive to a second current through the low-side switching transistor in a second mode when the low-side switching transistor is turned on and the high-side switching transistor is turned off. The low-side current sense amplifier senses the second current through the low-side switching transistor and generates a current control signal to the high-side current sense amplifier in the second mode.
