摘要
提出了一种最大充电电流控制降压变换器,实现了高跟踪速度。在整个工作范围内,采用自适应延迟补偿方案使开关频率保持在850khz±2.5%以内。采用0.35 μ m CMOS工艺制作了集成降压变换器,并通过大量的测量验证了所有功能。
An Ultra Fast Fixed Frequency Buck Converter with Maximum Charging Current Control and Adaptive Delay Compensation for DVS Applications
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 850 kHz within plusmn2.5% across the whole operation range. The integrated buck converter was fabricated using a 0.35 mum CMOS process and all functions are verified by extensive measurements.
