Small Volume DCDC Voltage Reduction Module

Product Introduction:

1: Adopting new imported chips

2: The output current is 3A high, running for a long time for 2.1A, with sufficient margin.

3: New scheme design is adopted, and the circuit design does not require electrolytic capacitor and tantalum capacitor (electrolytic capacitor has a short life, and tantalum capacitor is in danger of explosion). Two large-sized solid-state ceramic capacitors (MCCs) currently used in high-end circuits.

4: The new scheme adopts synchronous rectification, and the circuit conversion efficiency is very high. The efficiency reaches 97.5% when 6.5V to 5V 0.7A, and 94% when 12V to 5V 1A, unlike some peers, the efficiency is only 60-70%. The efficiency test removed the voltage drop of the input reverse protection diode and fuse.

5: Adopting high current shielding inductance, ultra-low internal resistance, and maximizing conversion efficiency. Reduce heat generation.

6: Ultra small volume, 20 (length) * 11 (width) * 5 (height) millimeters, full mesh, small.

7: Ultra low quiescent current, quiescent current 0.85 mA. Connect to the car battery without adding a switch, and can be connected to the cigarette lighter cable or the ACC power cord.

8: The output integration can adjust the fixed voltage. The fixed output is not customized. It can be directly spot welded on the board. The voltage is very useful. It can be adjusted with a potentiometer. It is very versatile

9: Integrated enable port, default to working mode, low level off, convenient for control

10: It can be used to replace the 78 series linear regulators, such as 7805, 7812, and so on.
