The TPS8269xSIP device starts operation when EN is set high and starts up with the soft start as previously described. For proper operation, the EN terminal must be terminated and must not be left floating.

Pulling the EN terminal low forces the device into shutdown. In this mode, all internal circuits are turned off and VIN current reduces to the device leakage current, typically a few hundred nano amps.

The TPS8269xSIP device can actively discharge the output capacitor when it turns off (See Device Comparison table). The integrated discharge resistor has a typical resistance of 100 Ω. The required time to ramp-down the output voltage depends on the load current and the capacitance present at the output node.
