ABSTRACT:
Improvements in the level of integration of a core buck and/or boost DC-DC voltage regulator sub-circuit lead to a lower manufacturing cost structure, an improved performance from lessened intrinsic parasitic resistance, a smaller die size and, thus, higher wafer yield. Further, by integrating certain components on-chip, the cost and complexity of the conventional hybrid circuit implementation is improved.
