Feature
*Adopt a new solution design. Circuit design does not require electrolytic capacitance.This improves security. Essence Two large-scale solid ceramic capacitors (MCC) used on high -end circuits are currently used.
*The circuit conversion efficiency is very high. When 6.5V to 5V 0.7A, the efficiency is as high as 97.5%, and the 12V to 5V 1A also reaches 94%.
*Using large current shielding inductance, ultra -low internal resistance, improving conversion efficiency. Reduce the heat.
*Ultra -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 ACC power line.
*Output integrated adjustable 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. It can be used to replace the 78 series linear regulator, such as 7805 7812 and so on.
