Description
Product Overview
The 3.7V to 5V 2A Step-Up Boost Converter Board is a compact, high-efficiency power module designed to convert the nominal voltage of a single lithium-ion or lithium-polymer battery (3.7V) into a stable 5V output suitable for powering USB devices, microcontrollers, sensors, and other 5V electronics . Whether you are building a portable power bank, powering an Arduino from a single 18650 battery, or creating a battery-powered IoT sensor, this module provides the essential voltage conversion needed for reliable operation.
At its core is a high-frequency DC-DC boost converter circuit that uses an inductor, a switching transistor, and a controller IC to step up the input voltage with up to 92% efficiency . The module is designed to accept a wide input range (typically 2.5V to 5.5V) and deliver a regulated 5V output at up to 2A peak current . This makes it an ideal solution for projects where a single lithium battery must power 5V logic devices, such as Arduinos, ESP32s, and Raspberry Pi Zeros .
Key Features
-
High-Efficiency Boost Conversion: Converts a 3.7V Li-ion battery input to a stable 5V output with efficiency up to 92%, minimizing power loss and extending battery life .
-
2A Peak Output Current: Capable of delivering up to 2A of output current (peak), suitable for powering a wide range of 5V devices including microcontrollers, sensors, and USB peripherals .
-
Wide Input Voltage Range: Accepts input voltages from 2.5V to 5.5V, making it compatible with single-cell Li-ion batteries (3.0V-4.2V), 3.7V LiPo packs, and even 3.3V or 4.2V power sources .
-
Built-in Protection Features: Includes overcurrent protection (OCP), overvoltage protection (OVP), undervoltage lockout (UVLO), and thermal shutdown to safeguard both the module and your connected devices .
-
Compact and Lightweight: Small PCB footprint (typically 42mm x 15mm) with a low profile, allowing easy integration into portable projects, enclosures, and battery packs .
-
Status Indicator LED: An onboard LED provides visual confirmation of output power, making it easy to verify operation at a glance .
-
Multiple Connection Options: Equipped with a USB-A port for direct output and/or solder pads (IN+, IN-, OUT+, OUT-) for flexible wiring, enabling use with battery holders, JST connectors, or custom wiring .
-
Switch-Mode Regulator Design: Uses high-frequency switching (typically 1MHz) for high efficiency and minimal external component size, resulting in a clean, stable output with low ripple .
