7.6 Switching Characteristics

Refer to the timing test circuit in Figure 16 (unless otherwise noted) for references to external components used for the test condition in the switching characteristics table. Switching characteristics shown below are only valid for the power-up sequence where VIN is already in steady state condition before the EN/UVLO pin is asserted high.
