Spesifikasi :
1. Use brand new original American imported chips , not domestic chips, disassemble chips.
2. The maximum output current is 3A , long-term operation is 2.1A, and the margin is sufficient.
3. Adopt a brand-new design , the circuit design does not require electrolytic capacitors and tantalum capacitors (the life of electrolytic capacitors is short, and tantalum capacitors may explode) Two large-size solid ceramic capacitors (MCC) currently used in high-end circuits are used .
4. The new solution uses synchronous rectification , and the circuit conversion efficiency is very high. The efficiency is as high as 97.5% when 6.5V turns to 5V 0.7A, and it  reaches 94% when 12V turns to 5V 1A. Unlike some peers, the efficiency is only 60-70%. . (The efficiency test removed the voltage drop of the input reverse connection protection diode and the fuse).
5. The use of large current shielding inductors, ultra-low internal resistance , maximize conversion efficiency. Reduce heat generation.
6.  20 (length) * 11 (width) * 5 (H) mm .
7. Ultra-low quiescent current, quiescent current of 0.85 mA . It is connected to the car battery without a switch, and can be connected to the cigarette lighter line or the ACC power line.
8. The output is integrated with adjustable and fixed voltage. The fixed output does not need to be customized. It can be directly spot welded on the board. The voltage is very useful and can be adjusted with a potentiometer, which is very versatile.
9. Integrated enable port, the default is working mode, low level is closed, which brings convenience to control
10. Can be used to replace 78 series linear regulators, such as 7805 7812 and so on.
