  • LTC3309A Feedback Resistor Value

    AnthonyT
    AnthonyT

    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,…
