LM2596S Adjustable DC-DC buck power module Stabilizer board 3A 12V/24V to 5V/3.3V

Connection port
IN+ enter positive IN- enter negative!
OUT+ Output positive OUT- Output negative

1, input voltage range: DC 3.2V to 46V It is recommended to use within 40V! The input voltage must be at least 1.5V higher than the voltage to be output. Can not increase pressure)
2, output voltage range: DC 1.25V to 35V continuous adjustable voltage, high efficiency (up to 92%) large output current 3A.

Module usage
1. Connect to the power supply (3-40V), the power tracing light is on, and the module works normally.
2, adjust the blue potentiometer knob (generally clockwise to turn the boost, counterclockwise to turn the buck) and monitor the output voltage with a multi-meter. Voltage required
Note:
3.It is recommended to use the current within 2. For long-term work, plus the heat sink (more than 10W output); Because it is a buck module, in order to ensure stable output, please keep the pressure difference small 1.5V.

Application case
1, car voltage regulator power supply, only to connect the input end of this module to the car cigarette holder power supply, you can adjust the potentiometer, the output voltage can be adjusted at 1.25-30V, for your mobile phone, MP3, MP4, PSP charging and many other equipment power supply, very simple and convenient.
2.. To power the electronic equipment, when the equipment needs 3-35V power supply and the corresponding voltage power supply in hand, this module can be used to conveniently adjust the voltage to the required voltage to solve the problem.
Note:
3. System operating voltage test, when doing projects can use this module to debug a variety of voltage test system operating voltage range, very easy and convenient.
