Hi, the data sheet of the LTC3309A recommends the typical range for the lower feedback resistor RB to be 40kohm to 400kohm. Can I use 10kOhm? Or it should be at least 40kOhm?
Thank you.

Hello,
I have a design using the LTC3309A. I am attempting to use the part as a 5V to 3.3V regulator.
My output voltages at this point are as follows:
No Load: 2.83V
100 Ohm Load: 1.5V
15 Ohm Load: 0.6V
Could my issue be related to schematic or layout? Both…
I have used LTC3309A from 5Vin to 3.3Vout, Frequency:2MHz(With RT connecting to Vin for Default value), and Vout setting for 3.3V; Sync/Mode is tied to Vin for Burst mode.
Question/Problem: I find the output voltage is dropped with the load is rised,…
