6. Einrichtung und Installation
The module has four main connection points: Input Positive (Vi), Ground (G), Output Enable (En), and Output Positive (Vo).
- Wie: Input positive (+) terminal. Connect your DC input voltage (2.6V - 5.5V) here.
- G: Ground (-) terminal. This is common for both input and output.
- De: Output Enable pin. This pin controls whether the output is active.
- Stimme: Output positive (+) terminal. The boosted DC output voltage (5V, 6V, 9V, or 12V) is available here.
Ausgangsvolumentage Auswahl

Das Ausgangsvolumentage of the module is selectable by bridging the corresponding pads on the back of the module. Ensure only one voltage pad is bridged at a time to set the desired output (5V, 6V, 9V, or 12V).
Enable Pin Operation

- To turn on the output: Connect the 'En' pin to Ground (GND).
- To turn off the output: Leave the 'En' pin not connected (floating) or connect it to the input voltage (Vi).
- The 'En' pin can also be controlled by a microcontroller (MCU): low level (GND) turns on output, high level (Vi or logic high) turns off output.
Schaltpläne
Application 1: With External Switch Control

In this configuration, an external switch is connected between the 'En' pin and Ground (GND). Closing the switch connects 'En' to GND, turning the output ON. Opening the switch disconnects 'En' from GND, turning the output OFF.
Application 2: No External Switch Required (Always ON)

For continuous operation where the output is always ON when input power is supplied, connect the 'En' pin directly to Ground (GND).
7. Bedienungsanleitung
- Erstinspektion: Before connecting power, visually inspect the module for any damage. Ensure all protective films are removed.
- Wählen Sie die Ausgangslautstärketage: If not pre-configured, bridge the appropriate pads on the back of the module for your desired output voltage (5 V, 6 V, 9 V oder 12 V).
- Eingangsstromversorgung anschließen: Connect your DC power source (2.6V-5.5V) to the Vi (+) and G (-) terminals.
- Control Output (if using 'En' pin):
- To activate the output, ensure the 'En' pin is connected to GND.
- To deactivate the output, ensure the 'En' pin is disconnected from GND (or connected to Vi).
- Last anschließen: Connect your load to the Vo (+) and G (-) terminals. Ensure your load's voltage and current requirements do not exceed the module's maximum output capabilities for the selected output voltage.
- Einschalten: Apply power to the input terminals. The module will boost the voltage to your selected fixed output.
- Ausschalten und Lagerung: After use, disconnect the input power. If not in use, store the module in a dry place, away from children.
8. Wartung
- Keep the module clean and dry. Avoid exposure to dust, dirt, and liquids.
- Regularly inspect the module for any signs of physical damage, loose connections, or overheating.
- Do not attempt to repair the module yourself. Refer to qualified personnel for any issues.
9. Fehlerbehebung
- Problem: Ausgangslautstärketage is lower than the nominal (expected) voltage.
- Lösung: The input power supply might be too low or unable to provide sufficient current. Ensure your input power source can deliver the necessary voltage and current for the desired output. Check the input voltage with a multimeter; if it drops significantly under load, the input source is insufficient.
- Problem: Keine Ausgangslautstärketage.
- Lösung:
- Check input power connections (Vi and G).
- Überprüfen Sie die Eingabelautstärketage liegt im Bereich von 2.6 V – 5.5 V.
- Ensure the 'En' (Enable) pin is correctly connected to GND to turn on the output. If it's floating or connected to Vi, the output will be off.
- Check for short circuits on the output (Vo and G). The module has Short Circuit Protection (SCP) which might temporarily shut down the output.
- The module might be in Over Temperature Protection (OTP) if it has been operating under heavy load in a high ambient temperature. Allow it to cool down.
- Problem: Module gets excessively hot.
- Lösung:
- The output load might be too high, exceeding the module's maximum current/power rating. Reduce the load.
- Sorgen Sie für ausreichende Belüftung rund um das Modul.
- Verify that the input power is greater than the output power, accounting for the module's own power consumption.
Aufmerksamkeit:
- Eingangsvolumentage cannot be greater than the maximum input range (5.5V).
- Output power cannot be greater than the maximum load for a long time.
- Input power must be greater than the output power, due to the module's own power consumption.
10. Benutzertipps
- Ausgangsvolumentage Auswahl: The module's output voltage (5V, 6V, 9V, or 12V) is set by bridging specific pads on the back of the board. Make sure to select only one output voltage.
- Enable Pin Control: For applications requiring an ON/OFF function, a latching switch or a microcontroller is recommended for the 'En' pin to maintain the desired state. A momentary switch would only activate the output while pressed.
- Power Source Quality: Use a stable and adequately powered input source to avoid output voltage drops, especially under load.
- Audioanwendungen: While not explicitly designed for audio, some users have reported concerns about potential sound interference when used with Bluetooth portable speakers. If using in sensitive audio applications, test thoroughly.
