ABSTRACT:
A voltage converter provides a desired voltage droop with load while avoiding output current sensing and active control/feedback circuits and avoiding excessive power dissipation from passive components by placing a sensing resistor in the low current, switched input circuit of the voltage converter. Therefore, the resistor conducts only when a switch controlling voltage conversion is conductive, generally at very low duty cycle and low current.
