Product details

2 MHz buck in a 1.4 mm² footprint

The Texas Instruments LM3671TLX-ADJ/NOPB is a synchronous step-down (buck) regulator delivering up to 600 mA from a 2.7 V to 5.5 V input rail. Its 2 MHz switching frequency lets you use a small inductor and ceramic output capacitor, shrinking the total solution to fit a 5-bump DSBGA package measuring 1.41 mm × 1.08 mm. The adjustable output ranges from 1.1 V up to 3.3 V, covering common core and I/O rails for portable and battery-powered gear. Synchronous rectification keeps efficiency above 85% across most of the load range, which matters when every milliamp of battery draw counts.

Industrial temperature range and active lifecycle

Rated for -40°C to 85°C ambient, the LM3671TLX-ADJ/NOPB fits outdoor telecom, factory sensors, and enclosure-mounted electronics that see temperature swings but not under-hood extremes.

Frequently asked questions

What is the closest functional equivalent to the LM3671TLX-ADJ/NOPB?

There is no pin-compatible second source listed. For a higher-current (3 A) automotive-grade buck with similar 2.1 MHz switching, the LMR33630APCQRNXRQ1 is a functional alternative but comes in a different package and requires a larger PCB footprint.
