Product description（6-20V）：


1, the output current is large 3A, long time running 2.1A, plenty of margin.

2, using a new program design, circuit design does not need electrolytic capacitors and tantalum capacitors (electrolytic capacitors have a short life, tantalum capacitors have the danger of explosion). Adopting the large size solid ceramic capacitors (MCC) used in high-end circuits, 3 of them.

3, the ripple is very low, 12V to 5V 3A only 10 millivolts or so, many counterparts of the ripple is up to 500 millivolts or greater, the equipment will cause an invisible damage, seriously lead to abnormal operation or damage to the equipment, IPHONE is very delicate.

4, the new program uses synchronous rectification, circuit conversion efficiency is very high, in the 6.5V to 5V 0.7A when the efficiency of up to 97.5%, 12V to 5V 1A when it reached 94%, unlike some counterparts only 60-70% efficiency. (Efficiency test removed the input reverse protection diode and fuse voltage drop).

5, the use of flat copper wire inductors, maximize the conversion efficiency. Reduce heat generation.

6, with output over-voltage protection, the input has a 1.5A fuse, the output 5V has a 300W TVS tube to do over-voltage clamping protection, protection of USB devices.

7, now peer USB buck module are not over-voltage protection, USB equipment, there is a very big security risk, you think if the buck module breakdown, 12V directly added to your IPHONE above, your IPHONE can also be spared?

8, using the new USB identification circuit, compatible with IPHONE, the vast majority of Android phones, IPAD.

9, the short head of gold-plated rimless USB, long service life, never ordinary USB interface can be compared.

10、Output voltage indicator (red)

11, input with reverse protection diode, input positive and negative poles are reversed will not be damaged, (the store test efficiency ignores the input diode and fuse voltage drop)

12, ultra-low quiescent current, quiescent current 0.85 mA. No need to add a switch to connect to the car battery, it can be connected to the cigarette lighter line or ACC power line.
