XL4005 5A Step Down Module

• Input Voltage : 4V-35V
• Output voltage (adjustable) : 1.23V-30V 
• Max output current : 5A
• Input must be 2.7V > than output
• Efficiency : Upto 92%
• Switching Frequency : 150kHz

Please note :
These modules are step-down modules, they will NOT produce an output voltage that is greater than the input voltage.
These modules are generally supplied adjusted to full output voltage and will therefore need
quite a lot of adjustment to produce low output voltages. If the output voltage appears to
be stuck at just under the input voltage, keeps turning the pot, it should get there eventually!
