These are really excellent dc dc converters and take quite a bit of misuse as i can attest. I even burned one out by misuse and replaced the capacitor and diode and back it sprang fine again! Gotta love these things!

Many of these products fail due to a faulty potentiometer. It is set to one end of the pot and cannot be adjusted, and therefore must be replaced for the device to function. This is not the only vendor with this problem, it is not the vendor's fault. The problem is with the poor-quality Chinese-made potentiometer similar to the Bourns 3296W-1-103 10K pot. Some of these devices use 50K pots (3296W-503) and have the same problem. There are vendors of better quality replacement pots available ranging from $1.50 through Allied to packages of 50 for $10 from Amazon. Also, fixed resistors may be substituted if you only need a particular voltage output. Standard 1/4 watt resistors are very cheap. In that case, both resistors should add up to around 10K to 50K Ohms. To determine the values, a good pot should be used, then measure the center to each end of the pot to get the correct 2 resistor values.Read full review

Be careful with this unit when using higher input and output voltages. Because of the way it steps the voltage up, Vsw peak on the XL6009 is the sum of the input voltage and output voltage and should be under 60V according the XSemi datasheet. I'm using in an application where the input voltage will vary between 20V and 27.6V (yes, from two 12 volt SLA batteries in series) to drive a 30V 350mA load and I found the inductors and capacitors to get uncomfortable hot. The inductors are in dis-continous current mode because for relatively low 33uH inductors. I replaced the inductors with 470uH (because I had some), and it now runs much cooler.

Works fine from approx. 4.5V and up. Used to power a 12V valve from batteries. Withstands short high current of 1.5A. Can be used for battery powered devices, has an enable pin. Pull down to low logic level to disable the converter (sleep mode). Sleep current around 40 uA.

This voltage "Module" is great and will regulate voltage very well. I bought one to use in a motorized bike and it keeps the voltage right at 12v nothing higher or lower. It can up or down the voltage to your needs and dont get hot if you keep under the 3amp mark. This along with my Rectifier that has smoothing caps to charge my SLA 12v battery so it has many uses and also a great price.
