8.3.1.3 ROFF
This pin is internally connected to an approximately 2.5-V DC source. A resistor (ROFF) to GND (pin 6) sets the discharge current of the internal-timing capacitor. The RON and ROFF pins set the switching period (TSW) and maximum-operating duty cycle (DMAX) according to the following equations:
Equation 2. 
Equation 3. 
Equation 4. TSW = tON + tOFF
Equation 5.
