Product Details
A Type-C USB 5V 2A Step-Up Boost Converter with USB Charger is a versatile and compact module designed to step up voltage from lower sources to a stable 5V output, ideal for charging and powering USB-powered devices. This kind of module is particularly useful in situations where you need to increase voltage from a battery or other power source that provides less than 5V (e.g., a 3.7V Li-ion battery) while ensuring a stable 5V output that can supply up to 2A of current, typically used for USB devices.
Key Features of the Power Management Circuit:
Automatic Output Turn-off for Low Load Current:
- Condition: When the load current is less than 50mA continuously, the module will automatically turn off the 5V output. This is typically implemented to save power and protect the device from running unnecessarily when the load is too small to require power.
Manual Control via External Key:
- Key Operation: The circuit supports an external switch (key) connected between the K point and the output negative pole. Here's how it works:
- Short press: Turns on the power display and the 5V output.
- Two consecutive short presses: Turns off the power display and the 5V output.
- This gives you manual control over the power output without needing to disconnect the power source physically.
- Key Operation: The circuit supports an external switch (key) connected between the K point and the output negative pole. Here's how it works:
Automatic Termination of Charging Cycle:
- When the charging current drops to 100mA after the battery reaches its final floating charging voltage (the voltage where the battery is fully charged but not overcharged), the charging cycle will automatically terminate.his helps ensure the battery isn't overcharged and maintains its lifespan.
Recharging When Battery Voltage Drops:
- If the battery voltage drops below 4.1V, the charging cycle restarts automatically. This is a protection feature to ensure the battery remains within a safe charge range.
Precharging for Low Battery Voltage:
- If the battery voltage is lower than 2.8V, the module will precharge the battery with a current of 180mA. This precharging feature is essential for reviving deeply discharged batteries in a safe manner, as low battery voltages could otherwise prevent normal charging.
USB-A Base Welding Position:
- The module comes with a USB-A base welding position on the back, which allows for manual installation. This feature likely refers to a place on the PCB where you can solder a USB-A port if needed, facilitating additional functionality like charging or power supply output through USB.
Supports Discharging While Charging:
- This feature enables the circuit to discharge the battery while charging. In other words, it allows for simultaneous power output and charging, which is useful when powering a device that uses the battery's energy while the battery is being recharged. This is a key feature for devices like power banks or battery-powered systems.
