FEICHAO LM2596 DC-DC Buck Converter 12V to 5V Step Down Module Power Supply 1.25-37V 3A
Note: The input and output can not be reversed, reverse might burn chips;This is a step-down module, the input voltage must be higher than the required output voltage.
Electrical parameters:
Input: DC 4.0~40V (input voltage must be more than the output voltage, can not be higher than boost 1.25v.)
Output: 1.25V~37V continuously adjustable. (The input voltage must be 1.5V higher than the output voltage)
High conversion efficiency, an average of 88% (efficiency is related to input, output voltage, current, and pressure difference)
Size: 44 (L) * 22 (W) * 14 (H) mm (including potentiometers)
Instructions:
Access to power (3-35V), adjust the blue potentiometer knob (clockwise rotation generally boost, buck counterclockwise rotation) and with a multimeter to monitor the output voltage reaches the required voltage.
Wiring:
1. Soldering, directly solder the power cord to the input (output) port;
2. Welding pins can be used by inserting pins through lead wires or inserting into holes on the board; or directly soldering on the PCB after adding pins.
Application examples:
1. The vehicle power supply, only need to enter this module termination point the car cigarette power supply, you can adjust the potentiometer, the output voltage can be adjusted in 1.25-30V, for your phone, MP3, MP4, PSP charging many devices powered, very simple and convenient.
2. The power to the electronic device when the device needs 3-30V power supply voltage corresponding to the hand while using this module you can easily put the voltage to the desired voltage and solve problems.
3. The system voltage test can be used to make this project a variety of debugging module voltage test system operating voltage range, very easy and convenient.
