PDT  
Note 3: The KILL turn-on blanking timer period is the waiting period  
immediately after the enable output is asserted. This blanking time allows  
sufficient time for the DC/DC converter and the μP to perform power-up  
tasks. The KILL and PB inputs are ignored during this period. If KILL  
remains low at the end of this time period, the enable output is released,  
Note 5: The enable lockout time is designed to allow an application to  
properly power-down such that the next power-up sequence starts from a  
consistent powered-down configuration. PB is ignored during this lockout  
time. This time delay does not include t
