TUSB8020B: Hub input supply current

Part Number: TUSB8020B
Other Parts Discussed in Thread: TPS82740B

Hello, 

Will a 200mA buck have enough headroom for the 3.3V supply? I am planning on using the TPS82740B module. 

The datasheet mentions a nominal input supply current of 93mA for 3.3V rail (USB3.0 Host / 1 SS and 1 HS device in U0), but does not state a maximum worst case. 

Thanks,
Amyi
