EC Buying 10Pcs Mini560 DC-DC Buck Converter Module 5A 3.3V Output, Step Down Voltage Regulator Board 6V–20V Input, High Efficiency Synchronous Rectification Power Supply Module

["This DC‑DC buck converter provides a regulated 3.3V output designed for powering low‑voltage electronics. It supports an input voltage range of 6V–20V and maintains stable conversion when the input voltage exceeds the required differential margin.","The module supports output current up to 5A under appropriate thermal conditions. For continuous operation above 4A, additional heat dissipation is recommended to maintain stable performance and operating temperature.","Designed with synchronous rectification and a switching frequency of approximately 500kHz, the converter achieves high energy conversion efficiency. This helps reduce heat generation and improve overall power utilization.","The switching regulation design provides relatively low ripple and low noise output, supporting stable operation of microcontrollers, communication modules, sensors, and other sensitive electronic components.","The compact PCB layout allows installation in space‑constrained applications such as embedded systems and portable devices. The module uses a non‑isolated buck topology suitable for DC voltage step‑down applications."]
