Description
  • weight: 485 g
Features:
1. Adopt new imported chips.
2. The maximum output current is 3A, running 2.1A for a long time, and the surplus is sufficient. 3A runs for about 20 seconds and the chip enters the overheat protection and restarts. It can work at 3A current by cooling and cooling the chip.
3. Using a new design scheme, the circuit design does not need electrolytic capacitors and tantalum capacitors (electrolytic capacitors have short life, tantalum capacitors are in danger of explosion). Three large-size solid-state ceramic capacitors (MCC) are used in high-end circuits.
4. Using non-isolated DC synchronous rectifier, the circuit conversion efficiency is very high. The efficiency is 97.5% at 6.5V to 5V 0.7A and 94% at 12V to 5V1A.
5. The use of integrated inductance, low internal resistance, greatly improve the conversion efficiency. It reduces calorific value and improves efficiency, and has lower calorific value than common shielded inductor.
Note:
1. In the case of low static current, 12V input and output 5V voltage, and strip LED lamp indicator, the static current is less than 0.45 mA.
2. Connecting to car batteries without switching, can be on the cigarett lighter line, or on the ACC power wire.
3. Output integration can be adjusted and fixed voltage. Fixed output is not customized. It can be directly spot-welded on the board. Special voltage can be regulated by potentiometer. It is very versatile.
4. Output with LED light indication, convenient and intuitive indication with voltage output.
5. With enabling ports, the default mode of operation is low-level shutdown, which brings convenience to control.
6. Can be used to replace 78 series linear regulators, such as 7805 7812 and so on.
