Module Information

• Adopt new design , circuit design does not require electrolytic capacitors and tantalum capacitors (electrolytic capacitor life is short, tantalum risk of explosion). Now with the use of high-end circuit of large-size solid ceramic capacitors (MCC) 3 Ke .
• Very low ripple, 12V turn 5V 3A only about 10 millivolts, many colleagues have reached a ripple 500 mV or more, the device will result in an invisible injury, a serious cause device is not working or is damaged, the IPHONE but very delicate .
• The new program uses synchronous rectification circuit conversion efficiency is very high, in turn 5V 0.7A 6.5V when efficiency up to% 97.5  , 12V turn 5V 1A, also reached 94%, unlike some peers efficiency is only 60-70%. (Efficiency test removed the input reverse polarity protection diode and fuse drop).
• Using flat copper wire inductance , maximize conversion efficiency. Reduce heat.
• First the whole network with output overvoltage protection , input fuse has 1.5A, 300W output 5V have done the TVS tube voltage clamp protection, to protect USB devices. 
• Now the buck peer USB modules do not have overvoltage protection, there is a very big security risk for USB devices, if you think about the step-down module breakdown, 12V directly added to your IPHONE above your IPHONE can survive it?
• Using the latest USB identification circuit, perfectly compatibleIPHONE, the vast majority of Android phones, IPAD .
•  Gold-plated USB boundless short head , long service life, not ordinary USB interfaces can be compared.
• Output voltage indicator ( red )
• Ultra-small size, 26.4 ( long ) * 15 ( width ) * 7.4 ( height ) mm, the whole network the minimum .
• Input with reverse polarity protection diode , the positive and negative reversed input will not be damaged, (We ignore the input diode test efficiency and pressure drop fuse)
• Ultra-low quiescent current, quiescent current of 0.85 mA . Connected to the car battery without adding switches can be connected to the cigarette lighter line or the ACC power cable line.
