DESCRIPTION (continued)
The current-limit threshold is adjustable with a single resistor connected to the device. The TPS4000x
controllers implement a closed-loop soft start function. Startup ramp time is set by a single external capacitor
connected to the SS/SD pin. The SS/SD pin is also used for shutdown.

(1) Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only,
and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions”
is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
