摘要：

The end-point prediction (EPP) scheme for voltage-mode buck regulators is proposed. Internal nodal voltages of the regulator controller are predicted and set automatically by the proposed algorithms and circuits. The settling time of the regulator can therefore be significantly reduced for faster dynamic responses, even with dominant-pole compensation. Proven experimentally by a voltage-mode buck regulator implemented in a 0.35-mu m CMOS technology, the reference-tracking speed using the EPP scheme is faster than the conventional buck regulator by about six times.
