Abstract: A boost-type converter circuit includes a pair of converter switches that are alternatively switchable on and off. An inductor is coupled to the intermediate point between the converter switches. A driver module controls switching on and off of the converter switches in respond to a comparator output signal. A reference signal line provides to the comparator a reference signal, and an output feedback line provides to the comparator an output feedback signal. These signals are compared to each other to generate the comparator output signal for controlling the driver module. A low-pass filter network is coupled to the inductor and configured to provide a ripple current which is a low-pass filtered replica of the current through the inductor. An injector circuit injects the ripple current into the reference signal line coupled to the comparator.

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.
