The LM2596 DC-DC Adjustable Step-Down Power Supply Module with Voltmeter is a DC-DC Step-down Adjustable Power Supply Module that is based on monolithic integrated circuit LM2596, ideally suited for easy and convenient design of a step−down switching regulator (buck converter). It is capable of driving a 3.0A load with excellent line and load regulation. This device is available in adjustable output version and it is internally compensated to minimize the number of external components to simplify the power supply design.
2. Touch the key to switch measuring input or output voltage, and has a light show which is being measured voltages
3. Power off memory function, show that road after power voltage values measured for the last time
4. Press the touch button for 3 seconds to turn off LED display, touch the button again to turn on the LED display
5. The band terminals, no iron can also be easy to use, and retention wire connection point
6. Input voltage 4.0-40V (input voltage to the output voltage must be higher than 1.5v.)
7. The adjustable output voltage range of 1.25V-37V continuously adjustable (input voltage must be higher than the output voltage to a high of about 1.5V)
8. The maximum output current up to 3A (heat sink required), normal and stable operating current of 2A
9. the internal oscillation frequency 150KHz, belonging to the second generation of switching voltage regulator, low power consumption, high efficiency
