I used during 4 weeks last summer without any problem this XL4015 based DC-DC Step Down Adjustable Power Supply Module.
I got a fistfull of these (5) for less than 10 € ebay.fr
I set them to 5,24 VDC, I stopped the screw of the potentiometer with nail varnish, add 2 drop of hot glue to mechanically strengthen the coil, then two sprays of Tropicoat on each side, install and forget ...
I guess the strong coil is responsible of the smooth functioning...
They are easy to install in my PiDesktop case, and benefit from the fan ventilation.
I use a second one to power both the LCD screen and USB hub...
Performance Parameters (suppliyer data) :
1、Input voltage range：4～38VDC (Note:input voltage not Exceeding 38V)
2、Output voltage range：1.25-36VDC Adjustable
3、Output current: 0-5A
4、Output power: 75W
5、High efficiency up to 96%
6、Built in thermal Shutdown function
7、Built in current limit function
8、Built in output short protection function
9、Input reverse polarity protection: None (if required, high current diode in series with the input).
