Product Description
Product introduction:
Output current limit 3A, long running 2.1A, ample margin.
A new design is adopted. The circuit design does not require electrolytic capacitors and tantalum capacitors (short electrolytic capacitor life and tantalum capacitors are at risk of explosion). The large size solid ceramic capacitor (MCC) used in the high-end circuit is 3.
The ripple is very low, 12V to 5V 3A only 10 MV, a lot of ripples in a lot of 500 MV or more, the equipment will cause a kind of intangible damage, seriously will cause abnormal equipment work or damage, IPHONE is very coddled.
The new scheme uses synchronous rectification, and the efficiency of circuit conversion is very high. When 6.5V turns to 5V 0.7A, the efficiency is as high as 97.5%, and 12V turns to 5V 1A when it reaches 94%. Unlike some of the peers, the efficiency is only 60-70%. (efficiency test removes the pressure drop of the input reverse protection diode and fuse).
The inductance of the flat copper wire is adopted to maximize the conversion efficiency. Reduce the amount of heat.
The first one has output overvoltage protection function, input 1.5A fuse, output 5V 300W TVS tube to do overvoltage clamp protection, and protect USB equipment.
Now, the USB depressurization module does not have overvoltage protection function, there is a very big security risk to the USB device. If you think of the breakdown of the hypotensive module, 12V directly added to your IPHONE, can your IPHONE survive?
The new USB identification circuit is perfectly compatible with IPHONE, the vast majority of Android mobile phones, and IPAD.
Short head gilded USB, long service life, no ordinary USB interface can match.
Output voltage indicator (red)
Input with reverse protection diode, input positive and negative pole connection will not be damaged, the test efficiency ignores the voltage drop of input diode and fuse.
Ultra low static current, static current 0.85 ma. Connected to the car battery without switch, can be connected to the cigarette lighter line, or ACC power cord.
