1: The use of new original US imports of chips, is definitely not a domestic chip, chip disassemble.
2: The maximum output current 3A, long time running 2.1A, sufficient margin.
3: The new program design, circuit design does not require electrolytic capacitors and tantalum capacitors (electrolytic capacitors, short life, tantalum capacitors have the risk of explosion). Used now high-end circuit with large-size solid-state ceramic capacitors (MCC) 3.
Ripple is very low, 12V 5V 5V only about 10 millivolts, many ripple counterparts have reached 500 millivolts or more, the device will cause an invisible injury, will lead to serious equipment failure or damage, but IPHONE Very delicate.
4: The new program uses synchronous rectification, circuit conversion efficiency is very high, the 6.5V to 5V 0.7A when the efficiency of up to 97.5%, 12V to 5V 1A reached 94%, unlike some counterparts only 60-70% . (The efficiency test removes the drop in input reverse protection diodes and fuses).
5: The use of flat copper inductance, maximize conversion efficiency. Reduce heat.
6: The whole network with the first output overvoltage protection, input 1.5A fuse, the output 5V 300W TVS tube overvoltage clamp protection, USB device protection.
Now peer USB step-down module has no over-voltage protection, there is a huge security risk on the USB device, you think about if the buck module breakdown, 12V directly in your IPHONE above, your IPHONE also spared it?
7: The latest USB identification circuit, perfect compatible with IPHONE, the vast majority of Android phones, IPAD.
8: short head gold-plated USB edge, long service life, not the ordinary USB interface can be compared.
9: Output voltage indicator (red)
10: ultra-small size, 26.4 (length) * 15 (width) * 7.4 (height) mm, the whole network of the smallest.
11: input with reverse diode protection, the input is not reversed will be damaged, (our test efficiency ignores the input diode and fuse pressure drop)
12: Ultra-low quiescent current, quiescent current 0.85 mA. Connected to the car battery without adding a switch, you can catch the cigarette lighter line, or ACC power line.
