Other Parts Discussed in Thread: LMZ31506, LMZ31710,
The LMZ31503 data sheet, as well as the LMZ31506 and LMZ31710 data sheets provide tables relating output voltage to required switching frequency (Table 2 on the 31503 data sheet). We will have a number of ADCs on my board. While the LMX31503 won't be powering the ADCs directly, I have never seen an instance where some of the switching noise didn't find its way into the output spectrum. We would like to be able to tune the switching frequency to place the switching noise outside of the signal of interest. The data sheet only provides specific switching frequencies for each output voltage, not a working range. How can I know what range of switching frequencies can be used to produce each output voltage?
