2 pcs LM2596S-ADJ 3-40V DC-DC Adjustable Step-Down Voltage Regulator Module 3A Buck Connector Description

① The module uses a high-efficiency (up to 92%) LM2596 chip with low heat generation and can easily handle more than 3 A (short-term) current. ② This module is machine-assembled and manufactured using reflow soldering. Each module also undergoes a two-hour aging test before shipping. ③ A stabilized power supply is integrated on the board. Simply connect the input of this module to the cigarette lighter socket for power and then adjust the potentiometer to power devices such as mobile phones. ④ It can be plugged into a pin via a wire, used on a perfboard, or soldered directly onto a printed circuit board after adding pins. ⑤ System working voltage test. This module can be used to set the working voltage range of various voltage test systems. ⑥ Module type: Non-isolated step-down module ⑦ Rectification method: Asynchronous rectification ⑧ Color: Blue-black ⑨ Material: PCB ⑩ Input voltage: 3.2 V-40 V ⑪ Output voltage: 1.25 V-35 V ⑫ Output current: 3 A (maximum) ⑬ Conversion efficiency: 92% (maximum) ⑭ Switching frequency: 150 kHz ⑮ Output ripple: 30 mV (maximum) ⑯ Load regulation accuracy: 0.5% ⑰ Voltage regulation accuracy: 2.5% ⑱ Operating temperature: -40C to +85C ⑲ Overall dimensions: 43 x 21 x 14 (L x W x H) (mm) ⑳ Notes: ㉑ 1. For continuous operation It is recommended to use a maximum current of 2.5 A and to add a heatsink (output over 10 W). As this is a step-down module, please maintain a minimum differential voltage of 1.5 V to ensure a stable output. 2. This module is an adjustable step-down module. The output voltage can be changed by adjusting the blue adjustable resistor on the module. The differential voltage between input and output is 2 V, and the minimum output voltage is 1.25 V. 3. The IN- (negative input), IN+ (positive input), OUT- (negative output), and OUT+ (positive output) terminals marked on the module must be connected correctly, otherwise the module may be damaged. 4. The module does not have a
