XL6009 2-Pack DC-DC Buck Boost Converter - Automatic Wide Voltage Regulator 5-32V to 1.25-35V;

Product Features

Auto start voltage will be pulled down to 7V less or smaller engine at high speed when the voltage up to 15V or higher. For 12V electrical work hard at work, this automatic buck module solves this problem , regardless of the input voltage is 5V or 12V or 32V, the output can be stabilized at 12V.

Parameters:
Wide input voltage: 5V-32V
Wide Output Voltage: 1.25V-35V
Built- 4A efficient MOSFET switches enable efficiency up to 94%; (LM2577 current is 3A)  high switching frequency of 400KHz, the ripple is smaller and smaller . (LM2577 frequency only 50KHz) 
Input Current: 4A(MAX); no-load 18mA (5V input , 8V output , no-load is less than 18mA. Higher the voltage , the greater the load current )
Output Ripple：50mV ( the higher the voltage , the greater the current , the greater the ripple ) 
Load Regulation：± 0.5% 
Voltage Regulation：± 0.5% 
Operating Temperature：-40 ℃ ~ +85 ℃ 
Size: 48.1x24.9x14.0 mm
Weight: 17g

Application:
1.Car regulato
2.solar photovoltaic
3.wind power and other applications of voltage instability

How to use
1.Access the power supply (5-32V), the power indicator light, the module is working properly.
2.Adjust the blue potentiometer knob (usually clockwise rotation boost, counterclockwise rotationStep-down) and monitor the output voltage with a multimeter to reach the required voltage.
3.A customer reflects the module output voltage can not be adjusted, always equal to the input voltage. When you encounter this problem, please first counterclockwise rotation potentiometer 10 laps above, and then use the module can be normal adjustment of the voltage
