Product Number: LTM4657
I have a question about the Rfeq of the LTM4657.
According to the DC2665B-C content, the recommended values for Rfreq are shown. We use 12v as input and output 1V, 1.8V, 3.3V, and 5V.
so
1. At 12V input -> 1V output, the Freq pin will be floated.
2. There is no Rfeq recommendation value for 12V input -> 1.8V. Can you recommend it?
3. I'm trying to use 336k (1000khz) for Rfreq on 12V input -> 3.3V and 223k (1250khz) on 5V. Is there a problem or any recommended value?
The above was obtained through the data sheet calculation formula.
best regard.
