Descritpion:
This Mini DC Buck Module uses synchronous rectification circuit conversion efficiency is very high, in turn 5V 0.7A 6.5V when efficiency up to 97.5%, 12V turn 5V 1A, they also reached 94%, unlike some others efficiency is only 60-70%. Ultra-low quiescent current, quiescent current of 0.85 mA. Connected to the car battery without adding switches can be connected to the cigarette lighter line or the ACC power cable line. The new design, circuit design does not require electrolytic capacitors and tantalum capacitors (electrolytic capacitor life is short, tantalum risk of explosion). Now with the use of high-end large-size solid ceramic capacitor circuit (MCC) 2 Ke. Big shielded inductor current, low resistance, to maximize conversion efficiency, reduce heat.
