Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix configuration against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure that the DSBGA-5 package dimensions align with the target PCB footprint and soldering profile requirements. Cross-reference the revision history for any changes in recommended operating conditions or testing parameters prior to finalizing the procurement order.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.5 V output is required within a 2.7 V to 5.5 V input range. The 600 mA current capability suits moderate load applications where board area is critical due to the small DSBGA-5 package. Consider the 2.6 MHz frequency for balancing electromagnetic interference and inductor size. Evaluate thermal performance under maximum load conditions to ensure operation within the specified temperature limits.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM3671 family of synchronous step-down converters designed for portable applications. The TL variant specifically denotes the DSBGA-5 package option, distinguishing it from SOT-23-5 versions like the MF series. The NOPB suffix indicates lead-free and halogen-free construction compliant with RoHS standards. This family targets designs needing high efficiency and minimal external component count.
