Overview

The TPS61023 is a synchronous boost converter designed for high-efficiency power management in portable devices, featuring an ultra-low minimum input voltage of 0.5V. It provides a compact solution for stepping up low-voltage sources to an adjustable output between 2.2V and 5.5V, supporting up to 3.7A switch current. Its low 20uA quiescent current and power-save mode make it ideal for extending battery life in single-cell or dual-cell applications.

Why Choose This Part

The device excels in low-power design with a 0.1uA shutdown current and a pass-through mode that improves efficiency when the input voltage exceeds the target output. Its 1MHz switching frequency allows for the use of small surface-mount inductors and capacitors, while the integrated SOT-563 package minimizes PCB footprint.

Applications

Electronic Shelf Labels
Provides efficient power conversion for e-paper displays and wireless radios from coin cell batteries.
Portable Medical Devices
Used in blood glucose monitors and pulse oximeters that require stable rails from varying battery voltages.
Battery-Powered IoT Sensors
Enables operation from a single Alkaline, NiMH, or Li-ion cell with true output disconnection during shutdown.
Supercapacitor Back-up
Efficiently boosts energy from discharging supercapacitors to provide a stable system supply.

Getting Started

To evaluate the TPS61023, engineers can use the TPS61023EVM-052 evaluation module which provides a pre-configured circuit for testing transient response and efficiency. When designing your PCB, ensure the input and output capacitors are placed as close as possible to the IC pins to minimize high-frequency switching loops.
