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

Features: 1.Input: DC 3V-35V(Input voltage must be higher than the output voltage of 1.5v or more) 2.Output: DC 1.5V-35V the voltage is continuously adjustable, the max output current is 3A 3.All use SANYO solid capacitors,36u thick circuit board,high Q value high power inductor,with output LED indicator light 4.If you work long hours, it is recommended to use the current within 2.5A.More than 2A need to add heat sink 5.High precision potentiometer,clockwise boost, counterclockwise buck 6.0.1uF high frequency bypass capacitor,effectively filter out high frequency noise Specification: Type: LM2596S DC-DC Step down power supply module Input voltage: 3.2V-35V Output voltage: 1.25V-35V Input current: 3A(Max) Conversion efficiency: 92%(highest) Output ripple: <30mV Switching frequency: 65KHz Working temperature: -45?~ +85? Dimension: 43mm * 21mm * 14mm Application: 1.Car power supply,only need to put this module input connected to the car cigarette lighter power supply,then you can adjust the potentiometer,the output voltage can be adjusted at 1.25-30V,provide power supply for your phone,MP3,MP4,PSP 2.Provide power to electronic equipment?when the device needs 3-35V power supply,with this module can be easily transferred to the required voltage Note: IN+: Input positive IN-: Input negative OUT+: Output positive OUT-: Output negative Input and output can not be reversed,otherwise it may burn
