Table 2. PIN DESCRIPTIONS (continued)
TERMINAL
DESCRIPTION
NAME NO.
Slow-start and tracking pin. Connecting an external capacitor to this pin adjusts the output voltage rise time.
SS/TR 28
A voltage applied to this pin allows for tracking and sequencing control.
Slow-start or track feature select. Connect this pin to AGND to enable the internal SS capacitor. Leave this
STSEL 29
pin open to enable the TR feature.
Inhibit and UVLO adjust pin. Use an open drain or open collector logic device to ground this pin to control
INH/UVLO 30
the INH function. A resistor divider between this pin, AGND, and PVIN/VIN sets the UVLO voltage.
