DC/DC Step Down Adjustable Voltage Converter Module with Display 3A LM2596

Description

Step-Down Voltage Regulator with Display LM2596 – 3.2V-35V 3A LM2596 step-down converter module. Input voltage from 3.2 V to 40 V. Maximum continuous output current 3 A. Output voltage adjustable from 3.2 V to 35 V. Built-in display shows the current output voltage. Product Description: LM2596 step-down converter 3,2V-35V 3A with display LM2596 step-down converter module. Input voltage from 3.2 V to 40 V. Maximum continuous output current 3 A. Output voltage adjustable from 3.2 V to 35 V. Directions of use The module has four leads as screw connectors: PIN DESCRIPTION IN+ Input voltage – positive pole. IN- Input voltage – negative pole (ground). OUT+ Output voltage – positive pole. OUT- Output voltage – negative pole (ground). The output voltage is selected from 3.2 V to 35 V using a potentiometer. Note that this is a voltage step-down circuit, so the output voltage cannot be higher than the input voltage. Features: Input: DC 3.2 V to 40 V (input voltage must be higher than the output voltage) Stable output, the output voltage is DC 3.2V to 35V, continuously adjustable, maximum output current is 3A. LED indicator output. Adjust the screw on top of the potentiometer clockwise or counterclockwise to increase or decrease the output voltage. With reversed polarity protection and short circuit protection, more safer to use; the display is very accurate. Specification of the LM2596 converter Input voltage: from 3.2 V to 40 V Output voltage: from 3.2 V to 35 V (lower than input voltage) Maximum continuous output current: 3 A (with cooling, up to 2 A without heat sink) LM2596 driver (documentation) Efficiency: less than 90% (depending on power consumption) Switching frequency: 150 MHz Four mounting holes with 3 mm diameter Display showing output or input voltage (pushbutton selectable) Board dimensions: 66 x 39 x 18 mm Weight: 23 g Useful links Documentation of the LM2596 chip
