You can ensure cold-start operation for Enpirion® EN53xxxx and EP53xxxx series devices by adding a delay on the ENABLE pin. This can be done by adding a 10-kR resistor between the AVIN and ENABLE pins, along with a 1-uF capacitor between the ENABLE and GND pins.
This information will be added to a future version of the EN53xxxx and EP53xxxx series device datasheets.
