Both converters can be enabled or disabled individually. Applying a logic HIGH signal at the enable pins (ENP for the boost converter, ENN for the inverting converter) enables the corresponding output. After enabling, internal circuitry necessary to operate the specific converter turns on followed by the soft-start period.

Applying a low signal at the enable ENP or ENN pin shuts down the corresponding converter. When both enable pins are low, the device enters shutdown mode, where all internal circuitry turns off. At this point, the device consumes shutdown current flowing into the VIN pin. The output loads of the converters can be disconnected from the input, see Section 7.3.4.
