LM2596S

Input 3.2V-40V Output 1.25V-35V
Input voltage range: DC 3.2V to 40V (the input voltage must be more than 1.5V higher than the output voltage. Boosting is not allowed)
Output voltage range: DC 1.2V to 35V voltage continuously adjustable, high efficiency (up to 95%), maximum output current of 3A.
Advantages: Adopting double-sided thickened high-quality black oil PCB board, all using imported SMD aluminum electrolytic capacitors, and high Q value high-power inductors. In addition, each board has undergone rigorous technical testing,
Specially designed 2 screw fixing holes. All four input and output pads are equipped with pin fixing holes;
Size: 43MM (length) * 20MM (width) * 15MM (height) (including potentiometer)
Attention: It is recommended to use a current of less than 2.5A and add a heat sink (output above 10W) for long-term operation;
As it is a step-down module, to ensure stable output, please maintain a minimum voltage difference of 1.5V.
Voltage regulation
Connect the power supply (3-40V), adjust the blue potentiometer knob (usually rotate clockwise to increase voltage and counterclockwise to decrease voltage), and use a multimeter to monitor the output voltage until it reaches the required voltage
Wiring method
1. Welding, directly solder the power cord to the input (output) port;
2. Solder pins can be inserted through leads or used on hole boards; Alternatively, after adding pins, they can be directly soldered onto the PCB.
Application examples
1. Car mounted regulated power supply, simply connect the input end of this module to the car cigarette lighter for power supply, and you can adjust the potentiometer. The output voltage can be adjusted between 1.25-30V, 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 needs a 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 doing projects, this module can be used to debug various voltage testing system working voltage ranges, which is very easy and convenient.
