    Hello Roadrunner,

    the LT8643S is already a 2nd generation part of our silent switcher family, with its integrated caps inside to reduce the size of the hot loop even a better part than the LT8640. And it offers 1A more output current. But both parts are new and should be available easily. LT8643S has a bigger package. Comparison of both is here (Together with the LT8640S):

    Linear Technology - Product Comparison 

    Buth beside that both parts will behave nearly similar in your application.

    I assume for a medical application the part should be fixed for your approval process, correct?
