Abstract
A switching power converter architecture that is efficient across its entire power range, regardless of load level, by partitioning the power devices into segments for optimal gate drive and providing a local variable-voltage driver for each power device segment. Power device segments may be selectively enabled or disabled based on the level of power to be delivered to a load. In addition, an adaptive gate drive scheme enables dynamic control of the Rand Qvalues for each power converter device so that the power devices may operate at the lowest Rvalue at or near maximum power levels for reduced conduction losses, at the lowest R×Qproduct value at mid-level loads for peak efficiency, and at the lowest Qvalue at light loads for reduced switching losses.
