LMR14020-Q1：Frequency vs Efficiency

Hi,

 1. It depend on the detailed input/output voltage and load current.  You can use WEBENCH(click here) to evaluate the efficiency under the detailed working condition.

 2. If you need a low cost 60V/2A device. For industrial application, I think you can consider LMR36520. The 1k price on ti.com is similar to LMR14020. And you can save a diode because LMR36520 is a synchronous buck.

     For automotive application, you can consider LM76002-Q1 (synchronous) and TPS54260-Q1(non-synchronous).

Thank you for comments !

I used  WEBENCH(click here) to evaluate the efficiency.

Would you please show me if you have pin FMEA? I look forward to working with you.

I need pin-FMEA or D-FMEA for LMR14020

Thank you.
