10.3.2 Programming Time
Total system programming time can be determined from the following equation:
TPROGR = TINIT + nPOL ×TPOL + nAD ×TAD
Where:
TPROGR
-
time interval from the instant when the DPM supply voltage exceeds DPM’s UVLO threshold until the
DPM issues the turn-on command. If the Auto Power-Up is enabled, and the turn-on delay is set to zero,
the output voltages start ramping up at the end of TPROGR interval
TINIT
TPOL
-
DPM initialization interval after the DPM supply voltage exceeds the UVLO threshold. TINIT=11.5ms.
Time required for programming and verifying of one POL converter. TPOL=26.5ms.
Time required for programming and verifying of one Auxiliary Device. TAD=7.5ms.
Number of POL converters in the system.

TAD
-
nPOL
-
nAD
-
Number of Auxiliary Devices in the system.
