Hello, I am working on a design where I have two LTM4676As in a configuration with a shared clock to generate 3V3, 3V7 and 1V8 from 12V with the 3V3 being generated on both devices. From page 53 of the datasheet (in particular table 7) I got that 750kHz is the recommended switching frequency in this case. However, under load, I noticed large voltage spikes (200mV) in sync with the switching frequency which disappeared when lowering it to 500kHz so I am in favour of using it. As this is not the recommended switching frequency does anyone know what these recommendations are based on or if there could be any downsides in using a lower frequency? For further context, I need (almost) the full output current but have a steady load with no large jumps in power.
