A 12V/24V-to-1V Shared Switched-Capacitor Multi-Inductor Multi-Output Converter with 90.9%/89.5%Peak Efficiency and Negligible Cross Regulation

In modern electronic systems like datacenter, automotive applications, etc., multiple low-voltage power rails are essential for high power efficiency and fine-grained power management. To minimize $\mathrm{I}^{2}\mathrm{R}$ losses in the power delivery network, a higher input voltage is preferred. As a result, a high-efficiency high-density power management unit with high VIN and low voltage conversion ratio (VCR, defined by $\text{Vout} / V_{\text{IN}}$), along with multiple outputs, is highly demanded.
