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
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 step-down power module that adjusts input voltage from 7-32V to an output of 0.8-28V. It has large aluminium heat sinks for better cooling and stable performance. With built-in capacitors and a strong magnetic coil, it works efficiently and reliably.
A TVS diode protects it from voltage surges, making it safe to use. This module is great for projects like battery charging, powering devices, or regulating voltage in cars, solar panels, and other equipment. It ensures a steady output even when the input voltage changes.

1. What size heatsink or cooling does this need at full 12A load?
The module already includes large aluminum heatsinks for heat dissipation. However, operating continuously at the maximum 12A/300W rating can generate significant heat depending on the input/output voltage, ambient temperature, and efficiency. For sustained high-current operation, provide good airflow around the heatsinks and monitor the module temperature. Avoid treating the 12A/300W figure as a guaranteed continuous rating under every operating condition.
2. Can this be used to charge a 12V battery?
Yes, it can be used as an adjustable DC-DC power source for battery-charging applications, but the output voltage and current must be set appropriately for the specific battery chemistry and charging requirements. This module should not be treated as a dedicated smart battery charger unless the required charging profile can be safely implemented externally. The current Robocraze page lists battery charging as one of its applications.
3. What's the maximum ripple/noise on the output?
A specific maximum output ripple/noise value is not currently provided in the product specifications. The module uses five 470µF/35V low-resistance capacitors to help stabilize the output, but the actual ripple can vary with input voltage, output voltage, load current, wiring, and measurement conditions.
