7805 small volume DC-DC step-down module 4-20V (12V to 5V3A) MINI efficiency 97.5% L7805 K7805 LM7805

Product introduction:

1: the outputCurrent 3 a, 2.1 A, long running allowance is enough.

2:A new design, do not need to electrolytic capacitor and tantalum capacitor circuit design

3: improve the conversion efficiency.Lower calorific value. 

4:Small volume, 20 (long) (width) * 5 * 11 mm (high).

5:Low static current, static current 0.85 ma., it can be connected to the car battery without the switch to connect the cigarette lighter line, or the ACC power line.

6:Output integration can reconcile fixed voltage, the output is not need to customize, can be directly on the board under the spot welding, very with voltage, can use potentiometer to adjust, strong commonality

7: integration enabled port, the default is working mode, low level off, bring convenience for control

Module parameters

The module properties:The isolation step-down module (BUCK) synchronous rectifier

The input voltage:DC 4 to 18 v

Output voltage:Integration can reconcile fixed output, can choose a fixed output voltage on the back

17 V adjustable range (0.8 -), a fixed voltage (1.8 V to 2.5 V, 3.3 V to 5 V and 9 V 12 V)

Output current:3 A (please note full heat), the actual test input 12 v output within 1.5 A need not special processing heat dissipation.
