LMZ30602: Question reg Rrt

Part Number: LMZ30602

Hi,

As per table 4 of the datasheet for 2.2Vout the recommended Rrt is 174kOhm. However when i created the sample schematic using WEBENCH the Rrt value came out to be 365kOhm. Which one is correct?

Thanks,

Uttara

    Hi Uttara,

    Thank you for pointing this to my attention. I would recommend following the datasheet's recommended values. In this case for a 2.2V output, the Rrt resistor should be 174kOhms for a switching frequency of 1.5MHz. I will contact the Webench team to address this discrepancy.

    Regards,

    Jimmy
