TPS92682-Q1: Low side PWM dimming

Part Number: TPS92682-Q1

I am trying to design a 100W CC dual channel common anode LED driver. I am looking at using the TPS92682 because it can support my voltage and power requirements and it has 2 channels. Because it will be used with common anode LED strips I would like to use a one channel as the current source on the anode and then use low side PFETs to PWM control each channel on the cathodes side of the LED strip. 

I see from the datasheet "The PDRVx output is a function of the internal PWM signal and is capable of sinking and sourcing up to 50 mA of peak current to control a high-side series connected P-channel dimming FET."

I'm wondering if it is possible to control the PFET on the low-side and what implications that would have? 

I also considered the TPS92205x as it supports common anode but I need something with software adjustable max LED current.
