LM2596S DC-DC step-down power module 3A adjustable step-down module.
Increase in the input and output terminals respectively X7R high-Q high frequency bypass capacitor, electromagnetic compatibility super!
? Input voltage range: DC 3.2V to 35V (input voltage must be higher than the voltage output to 1.5V or more can not be boosted.)
? Output Voltage Range: 1.25V to 30V DC voltage is continuously adjustable, high efficiency (maximum 92%) of the maximum output current of 3A.
Found 12V input, load regulation 5V 1A output current is lower than 1%
Note: The input and output can not be reversed, reverse might burn chips;
This is a step-down module, the input voltage is higher than the required output voltage;
? ? ? ? Output 2A or less long period of time without additional heat sink output current is greater than 2.5A (or output power greater than 10W) to work long hours please add heat sink.
Electrical parameters:
Input: DC 3.2V to 35V (input voltage must be more than the output voltage can not be higher than boost 1.25v.)
Output: 1.25V to 30V DC voltage is continuously adjustable, high efficiency and maximum output current of 3A.
Size: 41 (L) * 20 (W) * 14 (H) mm (including potentiometers) Taobao minimum with locating hole with LED indicator DC-DC
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.
1. welding, welded directly to the power line input (output) port;
2. solder pins, or pins can be inserted through the lead insertion use in tunnel plate; soldered directly to the PCB after another or add 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.
