Overview

The TPS63000 is a high-efficiency buck-boost regulator designed for devices powered by a single-cell Li-Ion or Li-Polymer battery. It can provide a stable output voltage from 1.2V to 5.5V, even when the input voltage from the battery drops below the set output level.

Why Choose This Part

The device features an automatic transition between buck and boost modes, ensuring seamless operation across the full battery discharge cycle. With a low 50uA quiescent current and a power-save mode, it maximizes battery life in low-power and standby states.

Applications

Single-Cell Li-Ion Battery Devices
Maintains a steady 3.3V or 5V rail as the battery voltage drops from 4.2V down to its cutoff.
Handheld Terminals
Provides efficient power for portable scanners and data collectors requiring tight voltage regulation.
Solar-Powered IoT Nodes
Handles fluctuating input voltages from small solar cells to charge supercapacitors or power sensors.
Portable Medical Devices
Supports reliable operation in compact, battery-operated diagnostic equipment.
