Abstract
A system has an input voltage source, a power stage coupled to the input voltage source, a load coupled to an output node of the power stage and a control circuit, the control circuit implemented on a semiconductor die and including: an error amplifier having a first input, a second input and an output; a voltage divider coupled to the output node and configured to provide an output voltage sense value to the first input of the error amplifier; and a programmable reference voltage circuit with an output coupled to the second input of the error amplifier. The programmable reference voltage circuit includes: a reference voltage source; scaling circuit components between the reference voltage source and the second input of the error amplifier; and a switch between the reference voltage source and the second input of the error amplifier. The control circuit is coupled to the power stage and is configured to generate a control signal for switches of the power stage.
