This compact DC-DC converter module provides automatic buck-boost regulation, helping maintain a stable output voltage even when the input voltage is higher or lower than the desired output.
It supports applications such as industrial power supplies, DIY smart power supplies and embedded system power, with conversion efficiency up to 90% and a maximum output current of 5A.
The board exposes Input+, Input-, Output+ and Output- connections, plus an output indicator and an output voltage regulation control. One DC-DC Buck Boost Converter Module (5A) is included.
Features:
- Automatic voltage regulation: Allows the input voltage to be either higher or lower than the desired output voltage while maintaining a stable output.
- High conversion efficiency: Up to 90%.
- Maximum output current: 5A.
- Integrated topology: Integrates DC-DC boost and buck.
Specifications:
- Input Voltage: DC 6～35V
- Output Voltage: DC 1.0～33V (Note: This board is an automatic boost-buck board, and the output voltage can be greater than or less than the input voltage)
- Conversion Efficiency: 90% (Measured when input 12V and output 19V/2.5A, efficiency is related to the input voltage, output voltage, and current)
- Maximum Input Current: 7A (Please leave margin for long-term continuous work)
- Maximum Output Current: 5A (please leave margin for long-term continuous work)
- Module Size: 70x39x32 mm (L x W x H)/ 2.76 x 1.54 x 1.26 inch
A practical module for makers and engineers needing flexible step-up/step-down DC voltage regulation in embedded and bench power projects.
Jargon buster
Plain-language definitions for the technical terms used above.
- boost converter
- A boost converter is a switching power circuit that raises a lower input voltage to a higher output voltage. It is used when a device needs more voltage than its power source provides, for example running a 5 V sensor from a 3.3 V supply.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
