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.

摘要： A multiphase DC-DC converter architecture, in which respectively different channels have different operational performance parameters. These different parameters are selected so as to enable the converter to achieve an extended range of high efficiency. The converter contains a combination of one or more fast response time-based converter channels, and one or more highly efficient converter channels in respectively different phases thereof and combines the outputs of all the channels. The efficiency of the asymmetric multiphase converter is higher at light loads (up to approximately 12 amps), enabling it to offer longer battery life in applications that spend most of their operating time in the leakage mode, as noted above.
