Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: All currents into pins are positive; all voltages are referenced to
GND unless otherwise noted.
Note 3: The Enable Lock Out time is designed to allow an application to
properly power down such that the next power up sequence starts from a
consistent powered down confi guration. ⎯ P ⎯ B is ignored during this lock out
time. This time delay does not include t

Note 5: The ⎯ K ⎯ I ⎯ L ⎯ L turn on blanking timer period (t
waiting period immediately after enable output is asserted. This blanking
time allows suffi cient time for the DC/DC converter and the μP to perform
power up tasks. The ⎯ K ⎯ I ⎯ L ⎯ L , ⎯ P ⎯ B and UVLO inputs are ignored during this
period. If ⎯ K ⎯ I ⎯ L ⎯ L remains low at the end of this blanking period, the enable
output is released, thus turning off system power.
