Terminal for resistor bridge feedback
The SS terminal is used to enable soft start and to control on/off operation of the IC output,
VO (see figure 2). If neither soft start nor on/off control is used, leave pin open.
To enable soft start, connect a capacitor between SS and ground. To control on/off
operation, connect an NPN bipolar transistor, in a TTL open collector output configuration,
SS

between the SS terminal and GND. Turn off is done by decreasing VSSL below its rated
level.
When both soft start and VO on/off are used, a protection measure such as current limiting
is required because, if the capacitance of C3 large, the discharge current of C3 flows
across the transistor for on/off operation. Because a pull-up type resistor is provided inside
the IC, no external voltage can be applied.
