1-10pcs LM2596S DC-DC 3A Buck Adjustable Step-down Power Supply Converter Module
Specifications:
Product name: LM2596 DC-DC Buck module
Input voltage: 3V ~ 35V
Output voltage: 1.5V ~ 30V
Output current: 3A( Max)
Conversion efficiency: 92% (MAX)
Output ripple: <30mV
Switching frequency: 150KHz
Working temperature: -45°C ~ +85°C
Size: 43mm*21mm*14mm (Long*Width*Hight)
Features:
1. The range of input voltage: 3V to 40V DC (input voltage must be higher than to the output voltage of 1.5V above. Can't booster)
2. The range of output voltage: 1.5V DC to 35V 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:
1. 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.
2. IN+ positive input IN- negative input!
OUT+ output positive OUT- output negative!
Note that input and output cannot be reversed. Reversing may burn it!
Wiring Method:
1. Welding, directly solder the power cord to the input (output) port
2. Solder pins can be inserted into pins through leads or used on hole boards. Alternatively, after adding pins, they can be directly soldered onto the PCB
Applications:
1. In car voltage regulator power supply, simply connect the input terminal of this module to the car cigarette lighter for power supply, adjust the potentiometer, and the output voltage can be adjusted freely between 1.5-30V, providing power for many devices such as your phone, MP3, MP4, PSP charging, etc. It is very simple and convenient.
2. Power electronic devices. When the device requires 3-35V power supply and the corresponding voltage power supply is in hand, this module can easily adjust the voltage to the required voltage, solving the problem.
3. System working voltage testing. When working on projects, this module can be used to debug various voltage testing system working voltage ranges, which is very easy and convenient.
