Abstract | This letter presents a high-power-density point-of-load dc-dc converter for 12/24 V input applications, using the proposed high voltage-low voltage separated hybrid switched-capacitor (SC) topology. By incorporating inductors between the SC networks in HV/LV domains, the design achieves reduced inductor dc current (IL,DC) at small voltage conversion ratios (VCRs), optimized switching and conduction losses, and extended duty ratio range, enabling the use of small-sized inductors with higher dc resistance and resulting in a compact system volume. LV switches handle most of the current conduction, reducing switching losses and silicon area for higher on-chip power density. The fabricated converter, using a 180-nm BCD process, generates 0.8-1.8 V output from 12/24 V inputs with a 3-A maximum load. Measured results show total IL,DC of 1.2 A at VCR 0.075 and 2 A load. The converter achieves a peak power density of 355 mW/mm3 with a power passive volume of 15.2 mm3. Peak efficiencies are 85% at 12 V input and 84.2% at 24 V input. |
