Can the TPS40140 Switcher Pro components be used for a design using the TPS40131?
Are there any changes, caveats, modifications needed?

    Hi Ed,

    As far as I can tell, the current sense amplifier gain is different for the two parts; TPS40131 datasheet suggest use Type III compensator, while TPS40140 suggest Type II. So I am afraid using the components from TPS40140 may have problem.

    Regards,
