ABSTRACT:
A switching regulator system and method for producing regulated output voltage and current in response to an unregulated input voltage, including a plurality of switching regulators connected in parallel and control circuitry to accomplish uniform loading of each of the switching regulators according to the rated current producing capacity of each regulator. The switching regulators each include a switching transistor, an inductor responsive to the switching transistor, a free-wheeling diode responsive to the inductor, and a comparator for providing an output signal representative of whether the regulated output voltage exceeds a threshold. The control circuitry poroduces a control signal repesentative of the logical OR of the comparator output signals. Each of the indivdual switching regulators includes buffer circuit responsive to the control signal and coupled to the base electrodes of the respective switching transistors for turning all of the switching transistors on and off substantially simultaneously in response to the control signal. The individual switching regulators thereby supply the output current of the switching regulator system proportinately to the designed current producing capacities of the individual regulators. For identical switching regulators, each will supply an equal current to the load. For circuits with unequal design capacities the switching transistors have equal duty cycles, thereby proportioning the load current from each regulator according to its designed current producing capacity.
