LMZM23600: step up and step down in one component

Part Number:LMZM23600

Hi

i have a system that the input voltage can be between 20-2V and I need to convert it to 2-6V.

the thing is that sometime the input is 2V and I need to convert it to 6V and sometimes the input is 20V and i need to convert it to 2V so the ranges are pretty big.

I need a component that can be a step up when needed and also a step down when needed and the output voltage should be adjustable between 2-6V.

is there such a component?

thanks in advanced.
