300W 20A DC-DC buck converter is a high-performance step-down power module designed for LED driving, battery charging, and DIY power projects. It features a wide input voltage range of 6-40V DC and an adjustable output voltage of 1.2 -36V DC, supporting both constant current (CC) and constant voltage (CV) modes. Equipped with high-quality electrolytic capacitors and dual 75V/80A MOSFE
Ts, the module ensures low ripple (50mV) and stable output. The dual heatsink design provides efficient heat dissipation, enabling reliable operation even at high loads. With up to 96% conversion efficiency, it minimizes energy loss during voltage regulation. The converter offers self-recovery short-circuit and over-current protection for safety. The 30A screw terminals allow easy and secure wiring. Compact size (60×53×27mm) makes it suitable for various space-constrained applications.
