ABSOLUTE MAXIMUM RATINGS
RECOMMENDED OPERATING CONDITIONS
TPS54310
SLVS412D – DECEMBER 2001 – REVISED FEBRUARY 2007
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
