Whyte had weighed in at 18st 2lbs 2oz, nearly eight pounds heavier than when he outpointed British heavyweight Dereck Chisora in a notable 2016 victory, but still lighter than the 18st 11lbs 22oz Browne.
The sixth saw Whyte claim his victory with a solid combination to unsettle Browne before throwing a chopping left hook, knocking out Browne unconscious centre-ring.
Browne needed treatment with an oxygen mask in the ring afterwards after being too easy a target for Whyte.
