DC-DC Buck Converter Power Module 3A Adjustable Step-Down LM2596 Voltage Regulator 24V to 12V 5V 3V

Specification:

Type: LM2596S DC-DC Buck Converter Input

Voltage: 3V-35V

Output Voltage: 1.25V-35V

Output Current: 3A

Max Transfer Efficiency: 92%

Max Output Ripple: Less than 30mV

Switch Frequency: 65KHz

Work Temperature: -45 to +85 degree

Celsius Size: 43x21x14mm (LxWxH)

Tips: 1. Input and output cannot be reversed, or it will burn the module.

2. Input voltage much be more than 1.5V higher than output voltage. Can not used to boost voltage.

3. After wire connection, first to turn a dozen times, then adjust the voltage by anticlockwise rotation.

4. It is recommended to use within 2.5A current for long time work, and need to add heat sink if the current exceeds 2A (output above 10W).

Wire Connection: 1. Solder, weld the power cord directly to the input (output) port.

2. Welding Pin, can insert the pin with lead wire or insert into PCB, or welding on the PCB directly with pin.
