Abstract
A switching DC-DC converter circuit includes a switching stage having an input node receiving an input voltage and an output node producing an output voltage. The converter includes feedback loop circuitry coupled to the output node of the switching stage to produce, at a respective output node, a control signal of the converter circuit as a function of a difference between the output voltage and a reference voltage. The converter includes test loop circuitry arranged between an output node of the feedback loop circuitry and the output node of the switching stage. The test loop, when enabled, sources a current to the output node of the switching stage or sinks a current from the output node of the switching stage as a function of a value of the control signal of the converter circuit. The feedback loop circuitry is calibrated during a test phase of the switching DC-DC converter circuit.
