Name: LM2596 DC-DC step-down module
Input voltage: 4V~35V
Output voltage: 1.23V~30V
Output current: 3A (Max) Conversion efficiency: 92% (MAX)
Output ripple:
Operating temperature: -45~+85 Dimensions: 43mm*21mm*14mm (length*width*height)
Note: IN+ input positive pole IN- input negative pole! OUT+ output positive pole OUT- output negative pole! Note that the input and output cannot be reversed, which may burn out! Input: DC 3V to 35V (the input voltage must be 1.5V higher than the output voltage, and it cannot be boosted) Output: DC 1.5V to 35V The voltage is continuously adjustable, high efficiency, and the maximum output current is 3A.
.Features: All use SANYO solid capacitors, 36u thickened circuit boards, high Q value high power inductors with output LED indicators. It is recommended to use the current within 2.5A for long-term operation, and a heat sink is required for more than 2A (output more than 10W); Because it is a step-down module, to ensure output stability, please maintain a minimum voltage difference of 1.5V.
Wiring method 1. Welding, directly weld the power cord to the input (output) port;
2. After welding the pins, you can insert p Features: 1. Input voltage range: DC 3.2V to 40V (the input voltage must be higher than the output voltage by more than 1.5V. It cannot be boosted)
3. Output voltage range: DC 1.25V to 35V adjustable voltage, high efficiency (92%), and the maximum output current is 3A. Instructions for use: 1. Turn on the power supply (3-40V), the power indicator light is on, and the module is working properly.
4. Adjust the blue potentiometer knob (clockwise rotation generally increases the voltage, counterclockwise rotation decreases) and use a multimeter to monitor the output voltage to reach the required voltage. Note: It is recommended to use the long-term working current within 2.5A, and at the same time increase the capacity heat sink (output above 10W). Because it is a step-down module, to ensure stable output, please maintain a minimum voltage difference of 1.5V.
