Product Description

Features:
1: Adopting a brand new original US imported chip, not a domestic chip, disassemble the chip.
2: Output current 3A, long-term operation 2.1A, sufficient margin.
3: With a new scheme design, the circuit design does not require electrolytic capacitors and tantalum capacitors (the electrolytic capacitor has a short lifetime, and the large-sized solid-state ceramic capacitors (MCC) used in the current circuit are three.
Ripple is low, 12V to 5V 3A is only about 10 millivolts, and many ripples in the same line have reached 500 millivolts or more, which will cause an invisible damage to the equipment, which will cause abnormal operation or damage to the equipment. IPHONE is very Delicate.
4: The new scheme adopts synchronous rectification, and the circuit conversion efficiency is always high. When the 6.5V turns 5V 0.7A, the efficiency is as high as 97.5%, and when 12V turns 5V 1A, it also reaches 94%. Unlike the peers, the efficiency is only 60-70%. . (The efficiency test removes the voltage drop across the input reverse-protection diode and fuse).
5: The flat copper wire inductor is used to improve the conversion efficiency. Reduce heat.
6: With output over-voltage protection function, input 1.5A fuse, output 5V 300W TVS tube for over-voltage clamp protection, protect USB devices.
Now the peer USB step-down module has no overvoltage protection function. There is a big security risk to the USB device. If you think that the buck module is broken down, 12V is directly added to your IPHONE. Is your IPHONE still spared?
7: Adopt new USB identification circuit, compatible with IPHONE, most Android phones, IPAD.
8: Short-head gold-plated borderless USB, long service life, not comparable to the ordinary USB interface.
9: Output voltage indicator (red)
10: small size, 26.4 (length) * 15 (width) * 7.4 (height) mm, full
11: The input has a reverse protection diode, and the input positive and negative poles will not be damaged. (The test efficiency of this shop ignores the voltage drop of the input diode and fuse)
12: Low quiescent current, quiescent current 0.85 mA. Connected to the car battery without a switch, can be connected to the cigarette lighter line, or ACC power line.
