The described module is a non-isolated step-up (boost) voltage converter with specific properties and applications. Here's a breakdown of its key features and potential uses:
Module Properties:
- Type: Non-isolated step-up (boost) module.
- Dimensions: 65mm (length) x 56.5mm (width) x 23mm (height).
- Input Voltage Range: 10V to 32V.
- Output Voltage Range: 12V to 35V (adjustable).
- Maximum Output Current: 6A.
- Maximum Input Current: 10A (Heat dissipation enhancements recommended if exceeding 10A).
Output Power:
- Natural Cooling: Up to 100W.
- Enhanced Heat Dissipation: Up to 150W.
- Compatibility: Can power 65W and 90W dual-core notebooks.
- Example Application: Can be used to power a 19V 3.42A notebook from a 12V battery.
Efficiency and Performance:
- Conversion Efficiency: 94% (measured at Input 16V, output 19V 2.5A).
- Output Ripple: Maximum of 2% within a 20MHz bandwidth.
- Operating Temperature: Industrial range from -40°C to +85°C. At temperatures above 40°C, consider reducing power usage or enhancing heat dissipation.
- Full Load Temperature Rise: Approximately 45°C.
- No-Load Current: Typically 25mA.
- Voltage Regulation: 0.5%.
- Dynamic Response Speed: 5% within 200 microseconds.
Protection and Safety:
- Short Circuit Protection: None. Suggests installing fuses and protection circuits at the input port.
Input Reverse Polarity Protection: None. Suggests using a series diode at the input port.
Applications:
- Adjustable Vehicle Power Supply: Can be used to create a DIY adjustable output vehicle power supply. Connect a 12V input, and the output can be freely adjusted between 14V and 35V. However, the output voltage cannot be lower than the input voltage.
- Car Laptop Power Supply: Connect it to a 12V power supply and adjust the output voltage to match your notebook's requirements.
Please note that due to the absence of certain protections (short circuit, reverse polarity), additional precautions are recommended when integrating this module into a circuit. It's also important to manage heat dissipation, especially when operating at higher power levels and temperatures.
