New product introduction:

1: The output current is 3A, and 2.1A is running for a long time, and the balance is sufficient.

2: Adopt a new solution design, circuit design does not require electrolytic capacitance and 钽 capacitance

3: Improve conversion efficiency.Reduce the heat.

4: Small volume, 20 (long)*11 (width)*5 (height) millimeter.

5: Low static current, static current 0.85 mAh.There is no need to add a switch on the car battery, which can be connected to the cigarette lighter line, or the ACC power line.

6: Output integration can be adjusted and fixed voltage. The fixed output is not customized. It can be welded directly on the board. It is very voltage. It can be adjusted with a potentiometer. The universality is very strong.

7: Integrated to enable portable port, default work mode, low level closed, which brings convenience to control
