LM2596 DC-DC Buck Module:

Name : LM2596 DC-DC Buck module

The output voltage : 1.25V ~ 30V

Output Current :3A( Max)

Conversion efficiency:92%( MAX )

Output ripple: <30mV

Switching frequency: 65KHz

Working temperature: -45~ +85°

Size :43mm * 21mm * 14mm(Long*Width*Hight)

Features:

1.
the range of input voltage: 3.2 V to 40 V dc (input voltage must be
higher than to the output voltage of 1.5 V above. Can't booster)

2.
the range of output voltage: 1.25 V dc to 35 V voltage adjustable, high
efficiency (92%) largest maximum output current is 3A.

Instructions:

1. Power (3-40V), power indicator light, the module is working properly.

2.
Adjust the blue potentiometer knob (clockwise rotation generally
boost,counter-clockwise rotationTurn down) and reach with a multimeter
to monitor the output voltage required voltage.

Note:

Current
work long hours is recommended for use in less than 2.5A, while adding
bulkHeat sink (10W output above),because it is the step-down module, in
order to ensure stable output Set,please keep the minimum 1.5V
differential.
