摘要: A peak-current control single-inductor dual-output (SIDO) DC-DC converter is proposed. The proposed SIDO DC-DC converter not only provides dual output sources (one buck and one boost outputs) but also has minimized cross regulation. Besides, a new hysteresis mode decided by a power decision circuit can effectively prevent SIDO converter from oscillating when power of buck is larger than that of boost. SIDO converter achieves high conversion efficiency at light loads. Experimental results show a high efficiency from 85% at light loads to 94% at heavy loads.
