I'm looking at a design for customer to use the FPWM version of LMR38020-Q1 (LMR38020FSQDDARQ1). I see the EVM is populated with the PFM version. Are there any changes needed to be made on the EVM board to use FPWM variant? I did not see any difference noted in datasheet or the EVM guide. Please confirm if we can swap the unit on EVM with LMR38020FSQDDARQ1 without any other BOM change (assuming 5V VOUT like EVM). Further, I see that besides FPWM at all loads, the Vref may also be slightly different for the 'FS' variant and that the part supports negative current limit. Are there any other differences to be aware of? Thanks!
