I need to convert 5V DC to 19V DC with a maximum output current of 1 amp. The most important criterion I need is maximum conversion efficiency -- I don't care about PCB area, quiescent current, or shutdown current.
I don't know which converter to choose -- LM2731, LM2735, LM2733, LM2735-Q1, LMR62014, LMR62421, LMR64010 all seem to met the input/output voltage and current requirements but it's unclear which one will provide maximum conversion efficiency or if there is a difference between those converters that i'm not understanding.
I tried http://webench.ti.com/ with the input/output voltage/currents and the output indicated that LM3481, LM3478, LM3488, and LM3481-Q1 have efficiency of 97% and TPS43061 has efficiency 96%.
I am very unsure how to decide between these parts -- can someone with more experience give advice/techniques/help on how to do so?
