Adjustable step-up step-down buck boost converter
As mentioned in the description a buck-boost converter board will keep a pre-set voltage even if the voltage is below (step-up) or above (step down) the pre-set value. It works especially great where the power source fluctuates a lot e.g. solar panels
This is called a Cuk converter a type of DC/DC converter that has an output voltage magnitude that is either greater than or less than the input voltage magnitude. It is essentially a boost converter followed by a buck converter with a capacitor to couple the energy.
Please note that the trim pot that is used to adjust the output of the module needs to be turned quite a few times before you can see a change in the output.

Rated at 1A, 3A for short periods with heatsink
In the non-isolated Cuk converter, the input and output circuits share the common ground. The non-isolated Cuk converter topology consists of DC input voltage source Vin, input inductor L1, one controllable switch S, energy transfer capacitor C1, diode D, filter inductor L2, filter capacitor C2, and load resistance R. This converter exchanges energy between the inductor L1, capacitor C1, and inductor L2 to convert input DC voltage to required output voltage level. A power transistor switch (S1) such as a MOSFET is used to control the amount of energy exchanged.
Very satisfied with this . Its doing the job as promised.
Very happy with whole order process and speed of delivery
Excellent. Great value for money. Works exactly as expected. Now my WiFi and fibre modem runs smoothly on my backup battery.
bought 2 of these.One is working fine ,other 1 non functional
Great module, super smooth output. Reliable and robust. I use it to power my Siesmo/MAgnetic field detector, which is used to find faults in underground electrical cables. A 3,7 Volt 18350 battery and a, and DC-DC XL6009 Auto Boost Buck(Cuk) Module, and Boost the output to
9Volt, which in turn is used, the to drive, and the 2 x very hi gain, low noise, Amplifiers, and a LM386 headphone amplifier, and metering circuits for sensing, faint acoustic sounds and magnetic fields. I Also use a second, and a DC-DC XL6009 Auto Module, which is to recharge the battery.
I highly recommend this little SMPS Buck and Boost regulator.
