DC-DC Step-down Module 3A Adjustable Buck Step-down Module LM2596 Voltage Regulator Board
Features:
1. Precision adjustable potentiometer, easy to use
2. Made of high-quality materials, with 0.1UF high-frequency filtering
3. Ultra-large current chip, stable performance
4. 01uF high-frequency bypass capacitor, effectively filters high-frequency noise
5. Small size, only 43mm * 21mm * 14mm, can be used in various vehicle-mounted products, electronic equipment power supply, etc.
Product parameters:
Input voltage: 3.2V~35V
Output voltage: 1.25V~35V
Output current: 3A (maximum)
Conversion efficiency: 92% (highest)
Output ripple: <30mV
Switching frequency: 65KHz
Operating temperature: -45℃~ +85℃
Dimensions: 43mm * 21mm * 14mm (length * width * height)
Input: DC 3V to 35V (the input voltage must be 1.5V higher than the output voltage. It cannot be boosted)
Output: DC 1.5V to 35V voltage is continuously adjustable, and the maximum output current is 3A with high efficiency.
Features: All use high-quality solid capacitors, 36u thickened circuit board, high Q value high-power inductor with output LED indicator
For long-term work, it is recommended to use a current within 2.5A. If it exceeds 2A, a heat sink is required (output above 10W);
Because it is a step-down module, in order to ensure stable output, please maintain a minimum voltage difference of 1.5V.
Precautions:
IN+ input positive pole IN- input negative pole!
OUT+ output positive pole OUT- output negative pole!
Note that the input and output cannot be connected in reverse. Reverse connection may burn out!
IN connects to input, out connects to output, and the positive and negative poles are not connected in reverse according to the markings on the board! After connecting, adjust the step-down counterclockwise, and rotate it more than ten times first!
1.3V - 35V 3A precision adjustable power module
Wiring method
1. Welding, directly weld the power cord to the input (output) port;
2. Welding pins, you can insert the pins through the leads or insert them on the perforated board for use; or directly weld them on the PCB after adding pins.
Application examples
1. Car-mounted voltage stabilizer. Just connect the input end of this module to the car cigarette lighter for power supply, and then you can adjust the potentiometer. The output voltage can be adjusted arbitrarily between 1.25-30V. It can power your mobile phone, MP3, MP4, PSP charging and many other devices. It is very simple and convenient.
2. Power electronic devices. When the device needs 3-35V power supply and the corresponding voltage power supply is in hand, this module can be used to easily adjust the voltage to the required voltage to solve the problem.
3. System working voltage test. When doing projects, you can use this module to debug various voltage test system working voltage ranges. It is very easy and convenient.
