摘要： A multi-phase converter has a plurality of voltage converter circuits connected in parallel; current sensors provided in the voltage converter circuits respectively; and a controller configured to calculate an estimated value of a total input current inputted to the multi-phase converter. The controller may be configured to output a notification signal that indicates an abnormality in one of the current sensors when a difference between a total sum of measured values of all the current sensors and the estimated value is outside a predetermined allowable range.

摘要： A power conversion circuit providing a regulated output voltage to a load can include a switching regulator with an input configured to be coupled to an input voltage source and an output configured to be coupled to the load. The power conversion circuit can further include a metered charge transfer converter, such as a charge pump or a switched or pulsed current source, having an input configured to be coupled to an input voltage source and having an output configured to be coupled to the load. A controller coupled to the metered charge transfer converter can be configured to operate the metered charge transfer converter to deliver energy to the load responsive to a dip of the regulated output voltage below a threshold caused by an increase in current drawn by the load. The metered charge transfer converter may be located closer to the load than the switching regulator.

摘要： A Charge Pump Buck Converter (CPBC) includes a BC including an inductor and a CP coupled in parallel. Control logic is coupled to a switch driver coupled to a power switch(es). Control circuitry includes a voltage sensor sensing Vout and a voltage level generator for generating a first voltage level coupled to the CP stage and a second voltage level coupled to a duty cycle/rate generator block providing an input to an under voltage (UV) monitor coupled between OUT and the control logic. The control circuitry disables the CP when Vout>a first Vout level and controls the BC to regulate to a second Vout level>the first Vout level. During handoff between CP and BC during power up if Vout drops below a UV threshold, the UV monitor block modifies an input applied to the control logic for increasing charging supplied to the inductor.
