WGCD 5PCS Mini DC-DC Buck Converter 3A Power Adjustable Step Down Module 4V 12V 24V to 5V 3A

Features: 1: Adopting a brand new imported chip. 2: Output current 3A, long-term operation 2.1A, sufficient margin. 3: With a new design, the circuit design does not require electrolytic capacitors and tantalum capacitors (electrolytic capacitors have a short lifetime and the tantalum capacitors are in danger of explosion). Two large-size solid-state ceramic capacitors (MCCs) are used on the high-end circuits. 4: The new scheme adopts synchronous rectification, and the circuit conversion efficiency is very high. When the 6.5V turns 5V 0.7A, the efficiency is as high as 97.5%, and when 12V turns 5V 1A, it also reaches 94%. (The efficiency test removes the voltage drop across the input reverse-protection diode and fuse). 5: Adopt high current shielding inductor, ultra low internal resistance to improve conversion efficiency. Reduce heat generation. 6: Ultra small size, 20mm * 11mm * 5mm/0.79 * 0.43 * 0.2inch (L * W * H). 7: Ultra-low quiescent current, quiescent current 0.85 mA. Connected to the car battery without the need for a switch, can be connected to the cigarette lighter line, or ACC power line. 8: The output is integrated with adjustable and fixed voltage. The fixed output is not required to be customized. It can be directly soldered on the board. It is very voltage-sensitive and can be adjusted by potentiometer. It is very versatile. 9: Integrated enable port, default is working mode, low level is off, which brings convenience to control 10: Can be used to replace 78 series linear regulators, such as 7805 7812 and so on.
