Applications
The TPS6282533DMQR is designed for space-constrained IoT sensors, wearable electronics, and wireless modules powered from a single-cell lithium battery or USB supply requiring a regulated 3.3 V rail at up to 2 A. Its 1% output accuracy makes it well suited for precision ADC and RF transceiver supply rails where supply variation directly impacts measurement or transmission performance. The 1.5 mm × 1.5 mm QFN package allows it to fit within densely packed module designs such as Bluetooth Low Energy beacons, NFC tags, and coin-cell-sized sensor boards.

Frequently Asked Questions
What output voltage does the TPS6282533DMQR provide, and how accurate is the regulation?
The TPS6282533DMQR provides a fixed 3.3 V output with 1% accuracy across load and temperature, meaning the output stays within ±33 mV of the 3.3 V nominal value, which is tight enough to power precision 12-bit ADCs and RF transceivers without an additional low-dropout post-regulator.
What is the input voltage range of the TPS6282533DMQR, and does it cover single-cell Li-ion discharge?
The converter accepts inputs from 2.4 V to 5.5 V, which spans the full single-cell Li-ion discharge range of 3.0 V to 4.2 V, USB 5 V bus, and a nearly-depleted 3-cell alkaline stack at about 3.0 V, giving designers flexibility to support multiple power source types without circuit changes.
How small is the TPS6282533DMQR package, and what total solution area should a designer plan for?
The device itself occupies a 1.5 mm × 1.5 mm 6-pin QFN footprint, and a complete solution including two 10 µF input/output capacitors and a 1 µH inductor fits within approximately 10 mm² of PCB area, making it one of the smallest 2 A buck converter solutions available for wearable and compact IoT designs.
What control mode does the TPS6282533DMQR use, and how does that affect output ripple?
The TPS6282533DMQR uses voltage-mode pulse-width modulation, which provides a fixed switching frequency that simplifies output filter design and enables a predictable output voltage ripple below 20 mV peak-to-peak with a 1 µH inductor and 10 µF capacitors at full 2 A load.
Is the TPS6282533DMQR compliant with REACH and RoHS regulations for export to European markets?
Yes, the TPS6282533DMQR carries both REACH Compliant and Pb-free (RoHS) designations, confirming that no substances of very high concern exceed 0.1% by weight and that lead content is below 1000 ppm, satisfying EU import requirements for consumer electronics, medical devices, and industrial equipment sold in European markets.
