Key Features

  • Wide input range of 2.5 V to 5.5 V covers single-cell Li-Ion, USB 5 V, and regulated 3.3 V rails for versatile portable and wearable power designs
  • Voltage-mode PWM control in a 6-pin SOT-23 (DRL) package minimises PCB footprint, enabling high-density regulators on IoT nodes and wearable devices
  • Synchronous rectification with integrated power switches eliminates the external catch diode, improving efficiency and reducing component count in the power stage

Applications

The TPS62A01ADRLR is designed for stepping down 5 V USB or battery rails to 1.8 V or 1.2 V core supplies in wireless IoT modules, wearables, and portable medical devices. The 2.5 V minimum input allows direct operation from a single-cell lithium-ion battery discharged to near end-of-life, extending usable runtime. Its tiny SOT-23-6 footprint and minimal external component count suit compact PCB designs where board area is the primary constraint.

Frequently Asked Questions

What input voltage range does the TPS62A01ADRLR support, and can it run from a single-cell Li-Ion battery?

The TPS62A01ADRLR operates from 2.5 V to 5.5 V input, which covers the full discharge curve of a single-cell Li-Ion battery (typically 2.7 V to 4.2 V). This allows the regulator to maintain a regulated output rail without a boost stage, simplifying the power tree in compact portable designs.

How does voltage-mode PWM control in the TPS62A01ADRLR differ from current-mode control for output filtering?

Voltage-mode control uses only the output voltage error to set the duty cycle, which generally requires a slightly larger output capacitor—typically 10 µF to 22 µF—to achieve stable phase margin compared to current-mode designs. However, it is less sensitive to inductor DCR tolerance, simplifying inductor selection and making the design more predictable over temperature in the 2.5 V to 5.5 V input range.

How small is the required PCB footprint for a complete TPS62A01ADRLR power stage?

The SOT-23-6 package measures approximately 2.9 mm × 1.6 mm, and a complete power stage needs only an input capacitor of about 4.7 µF, an inductor in the 1 µH to 4.7 µH range, and an output capacitor of 10 µF to 22 µF. The total solution area can fit within 25 mm² making it practical for wristband or coin-cell-sized PCB designs.
