Loop-handover technique for digitally controlled multiple-output dc–dc converters

摘要: The loop-handover (LHO) technique is proposed to overcome the problem of close-loop performance in digitally controlled single-inductor multiple-output dc–dc boost converters during start-up. presented utilises an existing clock source and requires only a small number blocks. It also occupies smaller silicon area, thus consuming low power increasing efficiency. validated with on-chip digital controller converter architecture using segmented delay line pulse width modulation. Experimental results show successful close loop reduced transients by simpler LHO technique.
