Efficiency 97.5% DC-DC Step-down Module 6-24v12v24v to 5v3a

(Description in Chinese and English for Details)

Description in Chinese:

Product Introduction:
1: Use Chips Instead of Disassembling Machines.
2: The Output Current Is 3A, and It Runs 2.1A for a Long Time, with Sufficient Margin.
3: Adopt New Scheme Design, Circuit Design Does Not Need Electrolytic Capacitor and Tantalum Capacitors (Electrolytic Capacitor Short Life, Tantalum Capacitors Are in Danger of Explosion). Three Large-Sized Solid-State Ceramic Capacitors (Mcc) Are Used in High-End Circuits.
Ripple Is Very Low, 12V to 5V 3a Is Only about 10 MV, and Many Ripple Waves in the Same Industry Reach 500 MV Or More, Which Will Cause an Invisible Damage to the Equipment, seriously, the Device Will Work Abnormally Or Damaged, but the iPhone Is Very Delicate.
4: the New Scheme Adopts Synchronous Rectification, and the Circuit Conversion Efficiency Is Very High. When 6.5V to 5V 0.7a, the Efficiency Is as High as 97.5%, and When 12V to 5V 1a, It Also Reaches 94%, unlike Peers, Some Efficiency Is Only 60-70%. (the Efficiency Test Removes the Voltage Drop of the Input Reverse Connection Protection Diode and Fuse).
5: Flat Copper Cable Inductance Is Adopted to Greatly Improve the Conversion Efficiency. Reduce Calorific Value.
6: Full Mesh with Output Overvoltage Protection Function, Input Fuse with 1.5a, Output 5V and 300W TVs Tube Have Been Protected by Pressure Clamp to Protect USB Devices.
at Present, Usb Step-down Module in the Same Industry Does Not Have Overvoltage Protection Function, Which Has a Great Potential Safety Hazard for Usb Devices. If Step-down Module Breakdown, 12V Will Be Directly Added to Your Iphone, can Your iPhone Survive?
7: The New USB Identification Circuit Is Adopted, Which Is Perfectly Compatible with iPhone, Most Android Phones and iPad.
8: The Short-Headed Gold-Plated USB Has a Long Service Life, Which Is Not Comparable to Ordinary USB Interfaces.
9: Output Voltage Indicator Light (Red)
10: Ultra-Small Volume, 26.4 (Length) * 15 (Width) * 7.4 (Height) mm
11: the Input Has a Reverse Connection Protection Diode, and the Input Positive and Negative Connection Will Not Be Damaged, (the Test Efficiency of Our Store Ignores the Voltage Drop of the Input Diode and Fuse)
12: Ultra-Low Static Current, Static Current 0.85 MA. It Can Be Connected to the Cigarette Lighter Line Or Acc Power Line without Adding a Switch to the Car Battery.
