Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when ordering. Confirm the 'C' grade corresponds to the commercial temperature range requirements of your design. Ensure compatibility with the VQFN-HR-12 package dimensions during PCB layout. Check moisture sensitivity level handling procedures prior to assembly to prevent damage during reflow soldering processes.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a wide input voltage range up to 36 V is required alongside a 2 A load capacity. The 2.1 MHz frequency is suitable for designs prioritizing smaller inductor sizes over ultra-low EMI. Compare against the LMR33620BRNXT if enhanced electromagnetic interference performance is critical for the application environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LMR33620 series of synchronous buck converters. It shares architectural similarities with other members like the LMR33630 but differs in maximum output current ratings. The CRNXR designation specifies the commercial grade variant housed in a leaded-free VQFN-HR-12 package, distinct from automotive qualified versions such as the LMR33620CQ5RNXTQ1.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LMR33620CRNXT serves as the cut-tape equivalent of the same functional device. For applications requiring lower electromagnetic interference, the LMR33620BRNXT offers ultra-low EMI characteristics within the same pinout configuration.
