Sursa in comutatie DC-DC LM2596 Step Down 1.23V - 30 V

1, the input voltage: 3.2-35 v

Adjust way: first right after the input power supply (3.2-35 v) between the output voltage with a multimeter to monitor and adjust potentiometer (general chronological booster, the backward turn step-down),

2. 1.25 30 v adjustable output the no-load commissioning) is recommended.

3, the output current, rated current 2 a, 3 a biggest (need to add heat sink), if the output power is greater than 15 w, suggested that combined with heat sink

4, conversion efficiency: up to 92% (the higher the output voltage, the higher the efficiency)

4, static power consumption is only about 3 ma.

5. Because it is step-down module, in order to guarantee the stability of the output, please keep the minimum 1.5 V differential pressure.
