This DC-DC power supply module is an adjustable step-down power converter with high quality, high power, high efficiency and stable performance. Input voltage 3.2-40V and output 1.25-35V with stable performance.

Features:
Can precisely regulate the output voltage for DC-DC buck. 
Excellent LM2596 DC-DC chip and 92% conversion efficiency.  
Adopt SANYO patch capacitance and shielding inductance, SMD machine SMT and reflow soldering tecnology.
Widely used in many kinds of electronic equipments such as monitoring and frequency modulation transmitter.
Stable and reliable, fair price and thickened circuit board. 

Function:
Used for vehicle-mounted regulated power supply - Only need to connecte this module input end to the car cigarette lighter for power supply, you can adjust potentiometer and the output voltage can be arbitrary adjusted at 1.25-30V, charging for your mobile phone, MP3, MP4, PSP, etc, very easy and convenient.
Power supply for the electronic equipment - When a device needs 3-35V power supply with voltage source standby, you can adjuste the voltage to the voltage required with this module and solve the problems.
Used for system operating voltage test - You can use this module to debug the various voltage test system working voltage range, very easy and convenient.

NOTE: 
1. The input and output cannot be reversed, otherwise it may be burnt out.
2. Measured 12V input, 5V output and 1A current, the load regulation rate is less than 1%.
3. This is the step-down module. The input voltage must be higher than the output voltage. 
4. When the output current is higher than 2.5A (or the output power is greater than 10W) and work for long work, please add heat sink.
