These are the ones to get! Excellent!
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!Verified purchase: YesCondition: New

Boost-Buck not functional
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.Verified purchase: YesCondition: New

Careful with higher input and output voltages
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.Verified purchase: YesCondition: New

Great power regulator
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.Verified purchase: YesCondition: New

Dangerous garbage that will likely catch on fire
I bought an earlier version of this XL6009 module from alice and upon powering it up with 5V it started putting out 54V on the other side which is 20V over the capacitor ratings. Mine are all missing components (the diode next to IN- for instance). The output voltage rarely bucks stably. With 5V in the lowest I can get it is 16V but sometimes it jumps around to 1.2V and then I can buck/boost. But it's not at all stable. If you open/close the power it jumps back up to 16V. Worse it's input voltage dependent. If I then switch to 3.3V it will reduce the output voltage by more than half. The newer picture looks complete but honestly I wouldn't bother. I bought 10 of these and they're all garbage. What a waste.Verified purchase: YesCondition: New

Very good product.
This is a very clever little circuit. It's just a tricky problem, if the input voltage drops below 3.4V, the output voltage rises to the maximum. I think this can be prevented by using the "enable" input and some cheap parts.Verified purchase: YesCondition: New

Here’s the scoop.
For voltage regulation is an atmosphere of a large variation of input voltage (pressure), this works great. I push mine to its limits and recommend the addition of a heatsink to protect the larger chip. the rectifier does get quite hot, which is a concern, but it has not failed.Verified purchase: YesCondition: New

Good product. Can improve w/63V output capacitor.
Capacitors are 50V. This is good, but the XL6009 can handle 60V. Therefore better if Output capacitor is 63V. Improving, increasing the output range.Verified purchase: YesCondition: New

Good but not very good
The voltage adjustment potentiometer works against instinct: anticlockwise for increasing and clockwise for decreasing. It seems not to whitstand no load: after a couple of hours with no load it became very hot and stopped working. I don't remember if it was stepping voltage up or down. A second unit has been working (with load) several days with no problemVerified purchase: YesCondition: New

OK to buy
I have modificated the converter to give me a 0 to 10 volt dimming signal for a LED driver, the input is 24 volt from the driver. this works fine. I use a "normal" potentiometer, there is a option for an external regulating or adjusting part underneeth the trimmer on the converter pcb Normaly 1,25 is the lowest output.Verified purchase: YesCondition: New
