TPS63020 High-Efficiency Automatic Buck-Boost Module – 4.2V Fixed Output Step Up/Down Power Regulator

Overview

The TPS63020 Automatic Buck-Boost Module is a high-performance power solution based on the Texas Instruments TPS63020 IC. It is designed for projects where efficiency and size are non-negotiable. While most converters waste energy as heat, this module utilizes a 2.4MHz switching frequency to provide a stable 4.2V output from an input range of 1.8V to 5.5V. This makes it the perfect companion for Single-cell Li-ion (18650) or Li-Po batteries, ensuring your device runs until the battery is completely exhausted.

Key Features

• Ultra-High Efficiency: Up to 95% efficiency significantly extends battery life compared to standard regulators.

• Seamless Transition: Automatically switches between buck (step-down) and boost (step-up) modes with no output glitch.

• High Current Capability: Capable of delivering up to 4A in Buck mode and 2A in Boost mode (at 3.3V/4.2V).

• Power Save Mode: Features a selectable “Power Save” mode to maintain high efficiency even at very light loads (perfect for sleep-mode sensors).

• Compact & Low Noise: The 2.4MHz frequency allows for tiny inductors and provides a cleaner output for sensitive radio (RF) components.

Technical Specifications

Why use TPS63020 instead of cheap modules?

• Battery Endurance: If your project runs on a battery, this module can give you 20-30% longer runtime than an XL6009.

• RF Sensitivity: If you are using a SIM800L or ESP32, the high-frequency switching of the TPS63020 creates much less interference with your wireless signals.

• Tiny Footprint: It is significantly smaller, making it ideal for wearables or compact IoT enclosures.
