Description

The Single Cell Lithium Battery Boost Power Module Board is a compact, high-efficiency power management module designed to boost the voltage of a single-cell lithium-ion battery to a stable output voltage, making it an ideal solution for IoT projects, wearable devices, and portable electronics.

Functionality

The module's primary function is to take an input voltage from a single-cell lithium-ion battery (typically between 3.0V and 4.2V) and boost it to a regulated output voltage of 5.0V, 3.3V, or 2.5V (selectable via jumper or pin selection). This allows devices designed to operate at higher voltages to be powered from a single-cell lithium-ion battery, ensuring efficient power management and prolonging battery life.

Key Features

High Efficiency: The module boasts an excellent power conversion efficiency of up to 95%, minimizing heat generation and energy loss.

Low Dropout Voltage: The module's low dropout voltage ensures that the output voltage remains stable even when the input voltage is close to the output voltage, providing a longer battery life.
Over-Current Protection: The module features built-in over-current protection, which prevents damage to the device and battery in the event of a short circuit or excessive current draw.
Short-Circuit Protection: The module is designed to protect against short circuits, ensuring safe operation and preventing damage to the device and battery.
Compact Design: The module's small form factor (typically 15mm x 10mm x 3mm) and lightweight design make it ideal for integration into compact IoT devices, wearables, and portable electronics.
Easy Integration: The module features a simple and convenient interface, with input and output pins clearly labeled, making it easy to integrate into a wide range of applications.
Low Quiescent Current: The module's low quiescent current (typically <1mA) minimizes standby power consumption, further prolonging battery life.

Pinout Explanation
The Single Cell Lithium Battery Boost Power Module Board is a compact, high-efficiency power management solution designed for IoT applications. The module features a high-performance DC-DC boost converter, overcharge protection, and short-circuit protection. Here's a detailed explanation of the pins and their connections:
Pin 1: VIN (Input Voltage)
Function: Connects to the positive terminal of the lithium-ion battery (typically 3.7V)
Recommended voltage range: 3.0V to 4.2V
Note: Make sure to connect the battery with the correct polarity to avoid damage to the module.
Pin 2: GND (Ground)
Function: Connects to the negative terminal of the lithium-ion battery and serves as the reference ground for the module
Recommended connection: Connect to the negative terminal of the battery and any other ground points in the system
Pin 3: VOUT (Output Voltage)
Function: Outputs the boosted voltage (typically 5.0V) for the load
Recommended load current: Up to 1A (depending on the module's specifications)
Note: The output voltage can be adjusted by adding a resistor network to the VIN pin, but be cautious of the maximum input voltage rating.
Pin 4: EN (Enable)
Function: Enable or disable the boost converter
Logic level: Active high (connect to VOUT or a logic high signal to enable the converter)
Note: Pulling the EN pin low will shut down the converter and enter a low-power mode.
Pin 5: N/C (No Connection)
Function: Not connected internally; leave this pin unconnected
Connection Structure:
To connect the pins properly, follow this structure:
1. Battery Connection:
Connect the positive terminal of the lithium-ion battery to Pin 1 (VIN).
Connect the negative terminal of the battery to Pin 2 (GND).
2. Load Connection:
Connect the load (e.g., a microcontroller, sensor, or other device) to Pin 3 (VOUT) for power supply.
3. Enable Connection (Optional):
If you want to control the boost converter's enable pin, connect Pin 4 (EN) to a logic high signal (e.g., VOUT or a digital output from a microcontroller).
4. Leave Pin 5 Unconnected:
Do not connect Pin 5 (N/C) to any other pin or signal.
Important Notes:
Make sure to follow the recommended voltage and current ratings for the lithium-ion battery and the load to avoid damage to the module or the battery.
Use a suitable wire gauge and layout to minimize voltage drops and electromagnetic interference (EMI).
The module may have additional components, such as capacitors or resistors, to filter the output voltage or adjust the voltage regulation. Be cautious when handling these components to avoid electrical shock or damage.
By following this documentation, you can properly connect the Single Cell Lithium Battery Boost Power Module Board and harness its high-efficiency power management capabilities for your IoT applications.
