Abstract
A buck mode power supply monitors the pulse load current for use as a scaled reference for comparison to a measured output current from each stage of the supply. A correction signal is generated for each stage by comparing the reference to the measured output currents. This result is compared to a second reference created from the system clock. A resulting second correction signal is used to alter the threshold reference voltage in a manner that provides proportional pulse width control to the supply output.
