An Inductively Assisted 3:1 Switched-Capacitor Ladder Converter with 93.7% Peak Efficiency across 0.6-1.2V Output Using a 73.9mΩ DCR Inductor
An inductively assisted SC ladder converter is introduced that employs a small inductor connected to the output side to enable continuous voltage conversion below the native SC converter discrete ratio. The inductor delivers a fraction of the load current rather than its entire value, facilitating the use of a small-size inductor with a large DCR. The fabricated converter in a $0.18 \mu \mathrm{~m}$ process achieves a 93.7% peak efficiency despite employing a small 0402 inductor with a $73.9 \mathrm{~m} \Omega$ DCR.
