ABSTRACT:
A “digital data stream,” “binary sequence” or word can be generated by a logic circuit such as a processor and the sequence can be converted to a series of pulses such that the content of the sequence can be utilized to accurately control/drive a plurality of power transistors. Accordingly, a regulated voltage can be provided through such a data type output of a processor. Thus, a standard processor that executes data processing operations can provide a low level logic signal as a serial digital transmission, possibly a four bit word, and control a power supply without significant modification. To achieve such a conversion the processor can be capacitively coupled to a voltage level shifter and a delay module to provide a plurality of power transistor drive signals. The converter can be wholly integrated onto a processor or motherboard to eliminate devices and stand alone assemblies that are commonly required in data processing systems.
