Procurement Notes

Verify the manufacturer designation carefully, as some distributor listings may incorrectly attribute this part to Murata Electronics while official documentation identifies Nisshinbo Micro Devices Inc. as the producer. Confirm the specific suffix TR-FE corresponds to the reel packaging format required for your assembly process. Ensure compatibility with the SOT-23-Wide-6 footprint during procurement planning.

Selection Notes

Select this component when an 18.5V input tolerance is required for step-down applications. The combination of PWM and VFM modes offers flexibility in efficiency management across varying load conditions. Consider the SOT-23-Wide-6 package constraints for PCB layout and thermal dissipation requirements relative to other available switching controllers in the portfolio.

Part Context

This part belongs to the R1225N series of switching controllers from Nisshinbo Micro Devices Inc. The series focuses on providing robust power management solutions with specific input voltage ratings. The R1225N162D-TR-FE variant specifically addresses higher input voltage needs compared to lower-rated siblings within the same product family line.
