Hi Anthony,That's indeed what seems to happen with the TPS5420.Any idea why this behavior does not occur on the breadboard?All components are exactly the same. Only wiring is different.Best regards,Ruud.
View ArticleForum Post: RE: Using TPS2053B as USB Switch
The question was, if this IC can be used as a USB switch. As it is not declared as special USB switch (like MAX1946), I was not sure if how the IC can "know", that it has to limit the current to 500 mA...
