PRODUCTION DATA.
TI recommends operating the device with input voltages above 4.5 V. The typical VIN UVLO threshold is 4.3 V, and the device may operate at input voltages down to the UVLO voltage. At input voltages below the actual UVLO voltage, the device does not switch. If EN is externally pulled up to VIN or left floating, when VIN passes the UVLO threshold the device becomes active. Switching is enabled, and the soft-start sequence is initiated. The TPS54560B starts at the soft-start time determined by the internal soft-start timer.
