摘要：
A buck converter with maximum charging current control in achieving high tracking speed is presented. An adaptive delay compensation scheme is employed to keep the switching frequency at 850kHz within +/- 2.5% across the whole operation range. The integrated buck converter was fabricated using a 0.35 mu m CMOS process and all functions are verified by extensive measurements.
