1 convertitore DC-DC switching di tipo step down incentrato sullo stabilizzatore     

LM2596S molto compatto misura solo 46x26 mm altezza 12mm   

Tensione di ingresso: da 4,75Vdc a 35Vdc      

Tensione di uscita: da 1,25Vdc a 26Vdc (regolabile tramite trimmer multigiro)    

Corrente di uscita: 2A      

 

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)

5, static power consumption is only about 6 ma.

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