[Realplay] LM2596S-ADJ DC-DC adjustable step-down module IN3-40V OUT1.5-35V Note that the input and output can not be reversed . Reverse may cost damage to circuit !
Input : DC 3V to 40V
Output : DC 1.5V to 35V voltage is continuously adjustable , high efficiency maximum output current of 3A.
Features : All solid capacitors using SANYO , 36u thick circuit boards, high-Quality inductors with high- output LED indicators
DC-DC 45 ( L) * 20 ( W ) * 14 ( H) mm
Note: long working hours is recommended for use in less than 2.5A current , while adding a heat sink (10W output above ) ;
As the buck module , in order to ensure stable output , keep a minimum 1.5V differential .
The voltage regulator
Access to power (3-40V), adjust the blue potentiometer knob ( clockwise general boost, buck counter-clockwise ) and use a multimeter to monitor the output voltage reaches the needed voltage.
Wiring
1 welding, soldering directly to the power line at the input ( output ) port ;
2 solder pins, the pins can be inserted through a lead or plug in the hole using the board ; soldered directly to the PCB or add pin after another .
Application examples
1 vehicle power supply , simply enter the module powered cigarette holder termination point on the car , you can adjust the potentiometer , the output voltage can be adjusted in 1.25-30V , for your phone , MP3, MP4, PSP and other charge many devices powered, very simple and convenient .
2 to the power electronic device , when the device requires 3-35V supply voltage of the power supply while the corresponding hands , you can easily use this module to the required voltage of the voltage and solve problems.
3 Operating voltage test system , you can use this module to do the project when debugging a variety of voltage test system operating voltage range , very easy and convenient
