LMR33630-Q1: What deference between LMR33630AQRNXTQ1 & LMR33630CQRNXTQ1 & LMR33630BQRNXTQ1

Hi Team,

As I know,


Their deference is FREQUENCY, if want to replace each other, need to pay attention to the following three points , Is there any error?, THX

  1. Whether the frequency meets customer needs
  2. Replace the IC and need to match the corresponding inductance(L)
  3. The frequency will affect EMI and needs to be verified by customers

    Hi Kygo

    Yes you are correct. 

    And when you replace the IC, except  the L, you will also need to pay attention to the Cout .The choosing of L and Cout have great relationship with the frequency. see datasheet 8.2.2.4 and 8.2.2.5.

    By the way ,under same current rate, the higher inductor value usually needs larger volume, and the package on the PCB board may have difference.

    Best regards.
