voltage and current requirements, such as delivering over 1A at voltages below 1V. This drives the need for efficient point-of-load DC-DC converter topologies capable of large step-down conversion with high current density, typically from a 12V input. Conventional single-phase buck converters often struggle to operate at wide voltage conversion ratios (e.g., VCR=12:1) and with high current (e.g., >1A), in part because the required inductance to process the full input voltage at a small duty ratio needs to be large, resulting in significant volume, as shown in Fig. 21.7.1 (top left). Hybrid converters (Fig. 21.7.1, middle left), which introduce flying capacitors to reduce voltage excursions across inductors [1-5], can help reduce inductor volume. However, in single-inductor hybrid designs, the output inductor still
