DC-DC Step Down Module 6-20V12V20V to 5V3A

Product Introduction:

1: Using chips that are not disassembled.

2: The output current is 3A high, running for a long time for 2.1A, with sufficient margin.

3: New scheme design is adopted, and the circuit design does not require electrolytic capacitor and tantalum capacitor (electrolytic capacitor has a short life, and tantalum capacitor is in danger of explosion). Three large-sized solid-state ceramic capacitors (MCCs) currently used in high-end circuits. The ripple is very low, with only about 10 millivolts for 12V to 5V 3A. Many ripple levels in the industry have reached 500 millivolts or greater, which can cause invisible damage to the equipment and seriously lead to abnormal operation or damage. IPHONE is very delicate.

4: The new scheme adopts synchronous rectification, and the circuit conversion efficiency is very high. The efficiency reaches 97.5% when 6.5V to 5V 0.7A, and 94% when 12V to 5V 1A, unlike some peers, the efficiency is only 60-70%. The efficiency test removed the voltage drop of the input reverse protection diode and fuse.

5: Adopting flat copper wire inductance to maximize conversion efficiency. Reduce heat generation.

6: The entire network is equipped with output overvoltage protection function. The input has a 1.5A fuse, and the output 5V has a 300W TVS tube for overvoltage clamp protection to protect USB devices. Currently, USB step-down modules in the same industry do not have overvoltage protection function, which poses a great safety hazard to USB devices. If the step-down module breaks down and 12V is directly applied to your IPHONE, can your IPHONE still be spared?

7: Adopting a new USB recognition circuit, perfectly compatible with IPHONE, the vast majority of Android phones, and iPad.

8: Short head gold plated borderless USB, with an ultra long service life that is incomparable to ordinary USB interfaces.

9: Output voltage indicator light (red)

10: Ultra small volume, 26.4 (length) * 15 (width) * 7.4 (height) millimeters

11: The input is equipped with a reverse protection diode, and the positive and negative poles of the input are reversed without damage. (The efficiency of our store's testing ignores the voltage drop of the input diode and fuse)

12: Ultra low quiescent current, quiescent current 0.85 mA. Connect to the car battery without adding a switch, and can be connected to the cigarette lighter cable or the ACC power cord.
