Abstract

A system includes an input voltage node configured to provide an input voltage. The system also includes a load and a switching converter coupled between the input voltage node and the load. The switching converter is configured to provide an output voltage to the load based on the input voltage. The switching converter includes gate driver circuitry and a comparator coupled to the gate driver circuitry. The switching converter also includes a constant ripple injection circuit coupled to the comparator. The constant ripple injection circuit is configured to provide a positive current sense signal and a negative current sense signal to the comparator based on the input voltage and the output voltage.
