PRODUCTION DATA.
In the TPS543C20A device, the soft-start time controls the inrush current required to charge the output capacitor bank during start-up. The device offers 10 selectable soft-start options ranging from 0.5 ms to 32 ms. When the device is enabled the reference voltage ramps from 0 V to the final level defined by VSEL pin strap configuration, in a given soft-start time, which can be selected by SS pin. See Table 1 for details.
