Abstract

A voltage regulator includes a power stage configured to produce an output voltage from an input voltage at an input voltage terminal, a shunt resistor connected in series between the input voltage terminal and the power stage, a first level shifting resistor connected in series between a first terminal of the shunt resistor and a first sense pin of the controller, and a second level shifting resistor connected in series between a second terminal of the shunt resistor and a second sense pin of the controller. The input current of the regulator is sensed as a function of the voltage across the shunt resistor, as shifted down by the level shifting resistors and measured across the sense pins. The input voltage of the regulator is sensed as a function of the current flowing through either one of the level shifting resistors, as measured at one of the sense pins.
