100% duty cycle controllers

What is a good way to search for parts that have 100% duty cycle capability?

Vin=12V,  Vout = 6- 12V  with external FETs.

    100% duty cycle is not a search parameter but there is a way to "trick" the system into searching for parts that might meet your requirement.  Using Power Quick Search, found at www.ti.com then click on Power Management, enter your Vin requirement and then in the Vout requirement, enter a value that is 100mV less than Vin.  From those search results, you must review each datasheet to determine if the IC supports 100% duty cycle.
