Abstract

Conversion efficiency degrades in case of heavy-to-light loading change since state-of-art overshoot reduction techniques simply dissipate redundant energy at the output of buck DC-DC converter. Thus, the proposed dual-mode ripple-recovered compensator (D-RRC) and multi-phase suppressing output overshoot voltage (MP-SOOV) technique uses 33nH bondwire inductance to recycle energy and provides 47.1mW/μs ultra-fast power-recycling rate to suppress overshoot voltage from 507mV to 95mV with 81.3% improvement when load changes from 1.7A to 0.3A. Experimental results show 93% high efficiency and highspeed operation with only tens of nano second on-time period.

具有47.1mW/μs功率回收率和93%峰值效率的多核处理器DC-DC变换器抑制输出过调电压技术

在负载从重到轻变化的情况下，转换效率会下降，因为最先进的超调降低技术只是在降压DC-DC变换器的输出处消散冗余能量。因此，所提出的双模纹波恢复补偿器(D-RRC)和多相抑制输出过冲电压(MP-SOOV)技术利用33nH键合线电感进行能量回收，提供了47.1mW/μs的超快功率回收速率，当负载从1.7A变化到0.3A时，过冲电压从507mV抑制到95mV，提高了81.3%。实验结果表明，该系统的运行效率高达93%，且运行速度快，开机时间仅为几十纳秒。
