A 2-Phase Soft-Charging Hybrid Boost Converter with Doubled-Switching Pulse Width and Shared Bootstrap Capacitor Achieving 93.5% Efficiency at a Conversion Ratio of 4.5 and vice versa in state-2 (at t3). As VDR34 is reused to charge C5 and C6, an additional drop on VDR34 will occur at t1 and t3. However, thanks to the proposed topology, M5 and M6 are relatively small since they have low voltage stress and small high-side (HS) currents (to be explained next). This reduces both the sizes of C5 and C6, and the VDR34 drop.
