current +/-5v rail generation circuit requires >1A supply to get started

this is the rail generation schematic:

here is inverting buck-boost from datasheet:

from the datasheet:

Also, the start-up input current of the buck-boost converter is higher than
the standard buck-mode regulator, and this may overload an input power source with a current limit less than
1.5A. Using a delayed turn-on or an undervoltage lockout circuit (described in the NEGATIVE BOOST
REGULATOR section) would allow the input voltage to rise to a high enough level before the switcher would be
allowed to turn on

tested added the delayed start up but still no luck creating negative rail with 1A supply....
