LM5166: Looking for similar component with higher output current

Part Number: LM5166
Other Parts Discussed in Thread: LM5085, TPS62135

I am using the LM5166 but need a regulator that can support a higher output current - at least 1.5A, ideally 2-3A.  The 100% duty cycle (due to the PFET high-side switch) is a critical requirement.  I have seen some controllers that use an external PFET, but unfortunately I cannot fit those solutions on my PCB. 

The synchronous rectifier is a nice-to-have but not a requirement.

Are you aware of any other regulators with an internal switch that can support a 100% duty cycle but with higher output current?
