Hello good afternoon.
I am interested with the EVB_RT9742AGJ5F-ND board.
It would be possible for the intensity output to be adjustable from 0.5 to 1A.
The power supply is 5V and the output is also 5V.
Thank you. Albert.

Hi Albert, thanks for your post. I am not entirely sure what you are asking but it sounds like you want a variable output? This Part is used as circuit protection and power management for USB power supply applications so its not really a full blown power supply. It would regulate loads of upto 5A so im not sure what you would be gaining by implementing in an adjustable feature. In anycase here is more info for it that may answer any further questions https://www.richtek.com/Design%20Support/Reference%20Design/UG9742AGJ5F?sc_lang=en
