TPS73125-EP: PWM enable pin to facilitate sipping off of battery

Part Number: TPS73125-EP

Good afternoon.....

I am using a high resistive battery source and would like to ramp up my voltage to my sensor through the TPS73125 by PWM the enable pin dynamically (not a fixed PWM).  This will allow me to control the rate at which charge goes into the board and effectively keep my battery from getting 'slugged'.  Can you tell me if I will damage the part at all by doing this?

Thx

Steve
