What is LM3671TL-1.8/NOPB used for?
The LM3671TL-1.8/NOPB is well suited for battery-powered portable electronics such as smartphones, tablets, and wearable devices where tight board space and high conversion efficiency are critical. It also serves as a point-of-load regulator in IoT sensor nodes and wireless modules that must sustain 1.8 V digital core rails from a single-cell Li-ion supply. Its ultra-compact DSBGA footprint makes it ideal for space-constrained designs that require a low-profile, highly integrated power solution.

Frequently Asked Questions
What is the input voltage range supported by LM3671TL-1.8/NOPB, and how does it relate to single-cell Li-ion batteries?
The LM3671TL-1.8/NOPB accepts an input voltage from 2.7 V to 5.5 V, which spans the full discharge curve of a single-cell Li-ion battery (approximately 3.0 V to 4.2 V). This makes it a direct fit for battery-powered applications without additional pre-regulation stages, simplifying the power architecture and reducing system cost.
How much output current can LM3671TL-1.8/NOPB deliver, and which load profiles benefit from its PFM mode?
The LM3671TL-1.8/NOPB can source up to 600 mA at the fixed 1.8 V output. Its pulse-frequency modulation technique improves efficiency at light loads below roughly 50 mA, making it advantageous for IoT devices and sensor nodes that alternate between active bursts and deep-sleep states with very low quiescent current draw.
How small is the LM3671TL-1.8/NOPB package, and what board space does it occupy compared to SOT-23 regulators?
The LM3671TL-1.8/NOPB comes in a 5-pin DSBGA package measuring approximately 1 mm x 1 mm, which is significantly smaller than the standard SOT-23-5 footprint of about 2.9 mm x 1.6 mm. This roughly 75 % reduction in footprint area is critical for ultra-compact wearables and multi-chip modules where every square millimeter of PCB space matters.
