LM2596s DC-DC Step down Power Supply Module 3A Adjustable Buck Module LM2596 Voltage Regulator 24V 12V 5V 3V

Wiring: IN+ input positive IN- input negative OUT+ output positive OUT- output negative 1. Input voltage range: DC 3.2V to 40V (The input voltage must be higher than the output voltage by more than 1.5V. 2. Output voltage range: DC 1.25V to 35V voltage is continuously adjustable, high efficiency (up to 92%) output current up to 3A. How to use the module: 1. Connect the power supply (3-40V), the power indicator light is on, and the module works normally. 2. Adjust the blue potentiometer knob (generally rotate clockwise to boost and counterclockwise to decrease) and use a multimeter to monitor the output voltage until it reaches the required voltage. Requires attention: 1. It is recommended to use the current within 2.5A for a long time work, and add a heat sink (above 10W output); because it is a buck module, in order to ensure stable output, please keep a small 1.5V dropout. Applications: 1. Vehicle regulated power supply, you only need to connect the input terminal of this module to the car cigarette lighter for power supply, you can adjust the potentiometer, the output voltage can be adjusted at 1.25-30V, charge your mobile phone, MP3, MP4, PSP, etc. Many devices are powered, very simple and convenient. 2. Power supply for electronic equipment. When the equipment needs 3-35V power supply and the corresponding voltage power supply in hand, this module can easily adjust the voltage to the required voltage to solve the problem. 3. System working voltage test, you can use this module to debug the working voltage range of various voltage test systems when doing projects, which is very easy and convenient.
