where
t
1 is the time to the first PWM pulse in seconds
t
2 is the time from the first PWM pulse until regulation in seconds
C
(SS) is the SS pin capacitor in F
I
(SS1) is the SS1 pin charging current in A, 7.5 A
I
(SS2)is the SS2 pin charging current in A,15 A
T
SS is the total soft-start time
The TPS40180 can function in a tracking mode, where the output tracks some other voltage. To do this, a
voltage divider is connected from the voltage to be tracked to GND, with the tap of the divider connected to the
SS pin of the TPS40180. See Figure 24. The capacitors C1 and C2 are required for two purposes. First they
provide a means for timing of overcurrent restart attempts. Second, they provide for matching output voltage
ramp up rate of the TPS40180 to the controlling external supply.
