TPS40190
SLUS658C –JULY 2005–REVISED JULY 2012 www.ti.com
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.

(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(1) The JEDEC High-K (2s2p) board design used to derive this data was a 3-inch x 3-inch (7.5-cm x 7.5-cm), multilayer board with one-
ounce internal power and ground planes and two-ounce copper traces on top and bottom of the board.
(2) The junction-to-case impedance is measured from the die to the thermal pad on the device package.
