10A DC-DC Step-down (Buck) Adjustable Constant Voltage Module

10A DC-DC Step-down (Buck) Adjustable Constant Voltage/Current Module

The 10A DC-DC Step-down Buck Converter Module offers a robust solution for power regulation, providing adjustable output voltage from 1.25V to 35V. Engineered for high-power applications, it delivers a continuous output current of up to 8A, with peaks up to 10A when adequately cooled. This versatile module features both constant voltage (CV) and constant current (CC) capabilities, making it ideal for a wide range of electronic projects. Its design incorporates a dedicated benchmark IC, high-precision current sensing, and four high-frequency capacitors to ensure stable performance and low output ripple. Dual heat sinks and independent MOS Schottky diode cooling enhance thermal management, allowing for reliable operation even under demanding loads. Precise voltage and current adjustments are easily achieved via onboard multiturn potentiometers. This module is a cost-effective and indispensable tool for makers, hobbyists, and professionals requiring a flexible and efficient power source.
