DC-DC 300W Boost Converter

The DC-DC 300W Boost Converter is a powerful and versatile voltage step-up module designed for a wide range of electronic, industrial, and automotive applications. This converter efficiently boosts lower DC input voltages to higher, adjustable output voltages, making it ideal for battery-powered systems, DIY projects, and power supply solutions that require stable, high-current output.

The 300W module features a robust PCB construction and high-quality electronic components, ensuring reliable performance and long-term durability. It supports an input voltage range of 5–40V DC and provides a continuously adjustable output voltage from 1.2V to 35V DC. With a maximum output current of 9A and a constant current range adjustable from .2A to 9A, this boost converter is suitable for powering high-demand devices and charging batteries. For optimal performance, a cooling fan is recommended when the power tube temperature exceeds 65°C, especially at higher loads.

Delivering up to 300W of output power, the converter maintains high efficiency and stable voltage regulation, with a compact size (6.5 x 4.8 x 2.4 cm) that allows for easy integration into various setups. The module does not include built-in short circuit or input reverse protection, so external fuses or diodes are recommended for safe operation. The converter’s dynamic response speed and low output ripple ensure clean, reliable power for sensitive electronics.
