Popis: | In mobile platforms, the 3-level buck converters are newly adopted in IF PMICs to support the fast charging mode. Despite the new adoption, we cannot avoid the ringing noises at the switch transitions which cause significant RFI issues in mobiles. In this paper, we propose a new modeling methodology for the SMPS ringing noises at the 3-level buck converter-based fast charging mode. The method can be used to estimate ringing noise spectrum and mitigate RFI risks at PCB level design. |
