| Abstract: | In a multi-output dc-to-dc converter with cross regulation, the noise generated in one of the multiple loads is transmitted to the other loads. It is called ?cross noise.? This cross noise is analyzed and experimental results are given. High-frequency equivalent circuits, which are composed of parasitic parameters and have several parallel and series resonances, are presented for cross noise in a two-output dc-to-dc converter. The frequency responses versus 100 kHz through 10 MHz noise are calculated from these equivalent circuits and agree well with experimental results. |
