PRODUCTION DATA
The enable rising edge threshold voltage is 1.08 V minimum and 1.22 V maximum. With EN held below that voltage the device is disabled and switching is inhibited. The IC quiescent current is reduced in this state. When input voltage is above the UVLO threshold and the EN voltage is increased above the rising edge threshold, the device becomes active. Switching is enabled, and the internal soft-start sequence is initiated as shown in Figure 8-7 to Figure 9-5.
