Abstract
A switching regulator provides load dependent output voltage regulation by sensing voltage drop across inherent DC resistance of the output inductor and secondary windings of power transformer with a first and second resistor and a capacitor and feeding back sensed voltage into an error amplifier for controlling the switching regulator. The regulator may be paralleled for more output current by connecting the outputs together and providing a common reference voltage to all the regulators.
