摘要: 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/mu s 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 high-speed operation with only tens of nano second on-time period.
