In datacenter, a single-stage conversion from 12-V V_IN to point-of-load PoL is favorable. Hybrid converters with 2:1 pre-stage switch-capacitor (SC), such as Double-Step-Down (DSD) [1] and flying capacitor C_F -Cross-Connected (CCC) [2], have higher power density and efficiency than the conventional buck. Additionally, these hybrid converters fits the 12V-to-PoL applications better than those works with more complex SC networks. Meanwhile, to conduct a large load current I_LOAD, a multiple-phase MP converter may be mandatory. In this work, we propose CCC-based MP hybrid converter, evolving from the 2-phase (2P) CCC as shown in Fig. 1. The 2P CCC has two CFS (C_FA, C_FB), two inductors L_A, L_B, two V_IN -stress switches M_A2, M_B2, four V_IN/2-stress switches M_A1, M_A4, M_B1, M_B4. We split the V_IN-stress switches into two V_IN/2-stress, e.g. M_A2 befomes M_A2' and M_A3'. The nodes between the split switches V_DCA, V_DCB are DC nodes =V_IN/2. Then, we connect the DC nodes as V_DC, and now the 2P converter has two symmetric sub-converters. Fig. 1 shows that with the same total power switch area, the simulated power conversion efficiency PCE is almost the same before and after the M₂ split. This decouples the two phases of the original CCC, and we can extend the number of phases N., Meanwhile, it inherits most CCC's benefits, such as higher efficiency and power density than the MP buck, and fast transient response than DSD [2]. Its sub-converter shares a similar topology to [3], but removes DC capacitor.
