Step 1: Function Introduction

①The voltage display
②Indicating input and output voltage area
③Function key:
Short press: input/output display options
Moderate press: Enter the fine-tuning state and increase or decrease the offset(the default is 0). when the voltage display      inaccurate use , you can short press to regulate, long press or long press to restore.
Long press: the state of low power consumption, the digital tube and the lights are out, the normal work of the module. Click the button again to restore. Normal display
④Adjust output voltage :
Clockwise----- increasing voltage
Counterclockwise----reduce the voltage
⑤schottky diode provides protection of reverse connection.
⑥High frequency capacitance to eliminate electric spark

Step 2: Diagram

Step 3: Testing Result:Input Voltage 5V

Test condition:
Input voltage:5V
Output voltage:6.2V

The actual testing results:
Output voltage:6.21V 
Output ripple:78mv(higher than the description, caused by the power supply by the preliminary analysis)

Step 4: Testing Result:Input Voltage 30V

Test condition:
Input voltage:30V
Output voltage:52.7V

The actual testing results:
Output voltage:52.3V
Output ripple: 1.76V(the value of voltage is unstable caused by the low output capacitance and low input current)

Note: When the voltage is much higher, the corresponding current will be higher (at least 3A). Otherwise the power supply will mistaken for short circuit and display abnormally.

    Question 6 weeks ago

    hello Guys,

    using the XL6009 I just got my Arduino burned. I used in combination with a Li-ion charging module and photocells. I tested yesterday the set-up and forgot to disconnect it during the night. Now what happened is: The voltage on the battery dropped below 3,5 Volt and in this moment the XL6009 produced an output of 35 Volt.

    I just tested this 6009 with a regulated power supply and I tested also a new module and both show the same problem. If the input voltage is above 3,5 Volt you can tune it pretty precise to 12 Volt and it keeps the 12V at any input voltage between 3,5 and 11 Volt, but once the input drops below 3,5 the output rocks up to 35-40V.

    Any ideas?

    Working with solar panel you can never be on the save side and guarantee that not a day wil come where the voltage drops below 3.5 V.

    when we connect load of 12V 2A the voltage suddenly fall down at 5V then what is Problem?

    Is this a boost converter or a buck? the title says its a step-up converter which would indicate that this maybe a boost converter. Also could you please tell us what the current ratings at input and output are? As in, if the input voltage is lower than the output voltage then by what margin does the output current reduce as compared to the input?

    Thank you for your good questions!

    It's a boost converter. And as it's described, the maximum input current is 4A. The output current is 0~4A which is according to the law of conservation of energy that it changes with the output voltage.

    Any unclear, please feel free to share with us.

    Best regards,
    ICStation Team

    The data sheet says it has Maximum 4A Switching Current and I suppose it is in the output stage. So, could this mean the input current could be higher? And thus, you can max out your power by increasing the input current as long as it will not reach or go beyond the maximum ratings?

    These are cool units. But When you wind the variable poteniometer too high they seem to pop, and then only pass through the input voltage. Has any one else found this issue?

    Better still does anyone know of to fix it, or are they toaseted?

    I suggest you to replace the potentiometer. rest of the circuit remains ok.

    You have not informed the AH capacity of your Battery. Any way the module is useful for currents less than 1Amp. If you exceed that limit,the module will become hot & some of the SMD components come off. In your case,though the module works, it may not last more than few seconds.

    You can get but current is reduced

    Do you have an IP65 version of this model? We need to use it in an LED streetlight which operates on 32V 600mah. We will input24V DC into the driver. Is the output self adjusting or is there a preset function??

    im using this chip in a home made battery bank with 18650 cells just to step up the 3.5 - 4.2 volts up from the cells to 5 volts but the output capacitor on the chip is getting really hot and im not sure why

    can i power a 100Watt single led using this XL6009 ? i am using a 19.5V 4.7A sony laptop adapter. 100watt led needs 3A at 36W. will there be any heating issues ?

    How many watts can the XL6009 produce handle. I am trying to power two 50 watt cob led chips (cheap eBay ones) , I have two of these XL6009's. I have some computer, phone AC/DC adapters and an old PC power supply. I really don't want to use the PC supply because these lights will be used in a grow shed. Plus I am not sure how to use it right. I have looked at 50 watt and 100 watt led drivers but this seemed cheaper. So I need to know how many watts can this produce and what power supply do I need to get this to power a 50 watt led chip. I also saw a 150 watt boost converter, if the XL6009 can't safely power a 50 watt Cob chip, can the 150 watt boost converter power 2, 50 watt led chips, and if so, can I use a PC adapter to run the 150W Boost converter or a 12v ac/DC adapter.
