Frequently Asked Questions
What is the input voltage range of TPS62002DGS and which battery types does it support?
TPS62002DGS accepts an input voltage from 2 V to 5.5 V, with a nominal of 3.6 V. This range covers single-cell lithium-ion batteries (nominally 3.7 V, down to 2.7 V discharged), as well as two-cell alkaline or NiMH packs, making it versatile for portable consumer and industrial designs.
How does PFM mode benefit TPS62002DGS in light-load conditions?
At light loads, TPS62002DGS automatically transitions from PWM to PFM (Pulse Frequency Modulation) control. In PFM mode the switching frequency drops significantly, reducing gate-drive and switching losses and improving efficiency to over 80% at load currents as low as a few milliamps, which is critical in always-on IoT nodes.
What package does TPS62002DGS use, and what is its approximate footprint?
TPS62002DGS is packaged in a 10-pin MSOP (S-PDSO-G10), measuring approximately 3 mm x 3 mm. This small-outline package fits tightly in portable PCB designs and requires minimal external components — typically an inductor, input capacitor, and output capacitor — keeping the total solution size under 25 mm².
What is the expected product lifecycle for TPS62002DGS, and is it suitable for long-production-run applications?
TPS62002DGS has a YTEOL (years to end-of-life) rating of 15 years, indicating Texas Instruments commits to supply this part for at least 15 more years. This makes it an excellent choice for industrial, medical, and infrastructure equipment with 10-to-15-year production and service lifetimes that cannot tolerate frequent component obsolescence redesigns.
