Abstract: A switching regulator circuit has a switching transistor actuated during a switching on phase of a duty cycle. The current flowing through an inductor of the switching regulator circuit is determined from sensing a transistor current flowing through the switching transistor during switching on phase and dividing the sensed transistor current by the duty cycle to generate an output signal indicative of the inductor current of the switching regulator circuit. The duty cycle is determined from a detected ratio of switching transistor turn on time during the switching on phase and switching transistor turn off time during a switching off phase as controlled by the duty cycle control of the regulator circuit.

Abstract: A switching regulator circuit has a switching transistor actuated during a switching on phase of a duty cycle. The current flowing through an inductor of the switching regulator circuit is determined from sensing a transistor current flowing through the switching transistor during switching on phase and selectively charging a capacitor of a switched capacitor circuit dependent on a current sense signal during the switching on phase.

Abstract: A switching regulator circuit has a high side (HS) transistor actuated during on time (TON) of a duty cycle. The output current of the switching regulator circuit is determined from sensing a transistor current flowing through the HS transistor during HS transistor on time (TON) and dividing the sensed transistor current by the duty cycle to generate an output signal indicative of the output current of the switching regulator circuit. The duty cycle is determined from a ratio of the on time (TON) and off time (TOFF) of the switching regulator circuit.
