Hybrid Regulated Ratio Tech for Intermediate Bus Converters

Click image to enlarge

Figure 1: HRR operation is similar to fixed ratio at lower Vin, but limits Vout at higher values of Vin

When designing the distributed power architecture for applications such as data centers, an isolated intermediate bus converter (IBC) might be used to take a nominal 48V or 54V input and generate a 10V to 12V bus for one or more downstream point-of-load (PoL) converters. In the past, there have been broadly tw
