Product Description

Maximum output current 3A, long-running 2.1A.
Using MP2315 design, with the use of high-end large-size solid ceramic capacitor circuit (MCC) 2 pcs.
The new program 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, it also reached 94%, unlike some peers efficiency is only 60-70%. (Efficiency test removed the input reverse polarity protection diode and fuse drop).
Using shielded high-current inductors, low internal resistance, to maximize conversion efficiency. Reduce heat.
Small size, 20 (L) * 11 (W) * 5 (high) mm
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.
Output Integrated adjustable and fixed voltage, fixed output does not need customization, direct can be very voltage, potentiometer can adjust, versatility is very strong on the board under the spot welding
Integration enabled pin, default mode, low close, bring convenience to control
Can replace linear regulators, such as 7805, 7812, and so on.
