6.3 Recommended Operating Conditions

over operating free-air temperature range (unless otherwise noted)
MIN MAX UNIT
Input voltage VIN 4.5 18 V
BST – SW –0.3 5.5 V
BST –0.3 23 V
FB, EN, MODE –0.3 5.5 V
PGND, AGND –0.3 0.3 V
Output voltage SW –0.3 18 V
SW(10 ns transient) –3.0 20 V
PG, VCC –0.3 5.5 V
IOUT Output current(1) 6 A
TJ Operating junction temperature –40 125 °C
Tstg Storage temperature –40 150 °C
(1) In order to be consistent with the TI reliability requirement of 100k Power-On-Hours at 105°C junction temperature, the output current should not exceed 6A continuously under 100% duty operation as to prevent electromigration failure in the solder. Higher junction temperature or longer power-on hours are achievable at lower than 6A continuous output current.
