YIDI 5pcs LM2596 DC to DC Buck Converter LM2596S ADJ 3A Voltage Regulator Adjustable Step Down Power Supply Module 24V 12V 5V

Specification:


Item Number: LM2596S 
Input Voltage: 3.2V~40V (The input voltage must be at least 1.5V higher than the output voltage.)
Output Voltage: 1.25V~35V
Output Current: Max 3A
Module Feature: Buck and non-isolated
Conversion Efficiency: Highest 92%(the higher output voltage, the higher efficiency)
Output Ripple: <30mV
Switching Frequency: 65KHz
Working Temperature: -45℃~+85℃
Size: 43mm*21mm*14mm(L*W*H)

How to use:
1. Access the power supply (3.2-40V), the power indicator light, the module is working properly.
2. Adjust the blue potentiometer knob (usually clockwise rotation boost, counterclockwise rotation Step-down) and monitor the output voltage with a multimeter to reach the required voltage.
3. If you encounter the problem that the module output voltage can not be adjusted, which always equal to the input voltage,
please counterclockwise rotation potentiometer 10 laps above, and then use the module normally to adjust the voltage.

Wiring:


IN+: Input Positive 
IN-: Input Negative
OUT+: Output Positive
OUT-: Output Negative

1. Welding, welded directly to the power line input (output) port;
2. Solder pins, or pins can be inserted through the lead insertion use in tunnel plate; soldered directly to the PCB after another or add pins.

Note:
1. The input and output interface can not be reversed.
2. Keep it under 2.5 A and use the heat sink when working for long hours.
3. This is a buck module. In order to ensure stable output, the input voltage must be at least 1.5V higher than the output voltage.

Packing: 5pcs/lot 

Factory default about 18V,turn the potentiometer around and reduce it by about 1V.
