xl4015 question
(1/1)
smile:
Hello, the datsheet for xl4015 shows that it's input is up to "Wide 8V to 36V Input Voltage Range"
http://www.xlsemi.com/datasheet/xl4015%20datasheet.pdf

I would like to use 27V PSU for this.

Currently it is used with 18V PSU, my questions is simple - will it heat more due to higher voltage input of 27V?
Jacon:
Nope - just look at the Figure 6 in your datasheet - the more voltage you apply, the better efficiency
you get, which means not much more heat generated  :-+

Thank for reply.

Do you know answer to this question regarding XL4015 and XL4016?
