12A 300W DC-DC Buck Converter Step down Power Module 7-32V to 0.8-28V

12A 300W DC-DC Buck Converter Step down Power Module 7-32V to 0.8-28V

The 12A 300W DC-DC Buck Converter is a high-power step-down module designed to regulate input voltages from 7-32V down to an adjustable output of 0.8-28V. Engineered for high-efficiency power delivery, it features dual large aluminum heat sinks for superior thermal management and a built-in TVS diode for surge protection. This module is specifically built to handle heavy loads, making it a reliable choice for charging battery banks, driving high-wattage LED arrays, or providing stable power in automotive and solar energy systems.

Features

• High-Power Output: Delivers up to 300W and 12A, providing ample power for demanding industrial and DIY applications.

• Dual Heat Sink Design: Features two oversized aluminum heat sinks to ensure stable performance and prevent thermal throttling during continuous use.

• TVS Surge Protection: Equipped with a Transient Voltage Suppressor (TVS) diode to safeguard the internal chip and connected devices from sudden voltage spikes.

• High Efficiency: Uses a 23mm large magnetic coil and pure copper wiring to achieve a conversion efficiency of up to 95%.

• Stable Power Delivery: Includes five low-resistance 470uF/35V capacitors in parallel to minimize output ripple and ensure a clean DC signal.

Key Points

• Safety Tip: For continuous operation at high power (above 8A or 65°C), it is recommended to add an external cooling fan to maintain component longevity.

• Precision Tuning: Features a multi-turn potentiometer for fine-grained control over the output voltage and current limits.

• Universal Compatibility: Ideal for regulating power from 12V or 24V batteries to run lower-voltage electronics like laptops, sensors, and microcontrollers.

• Integrated Protection: Built-in safeguards against over-temperature and short circuits (though external reverse polarity protection is advised).
