Can you name any commerical mppt controllers that are buck/boost?

Please set me straight...
MPPT controllers can be buck/boost topology designs and can operate over a much wider range of panels voltages than a PWM buck only topology. This equates to more operating time which ultimately increases system performance.
Here's one ->
MPPT Buck/BoostThere are many IC manufacturers that produce chips and designs for this topology. I am sure there are many others, all you need to do is to check for the lower input volatge.
