TPS61052
SLUS525 – MARCH 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.

(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.
(2) All voltage values are with respect to network ground terminal.
(3) In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may
have to be derated. Maximum ambient temperature (T
A(max)
) is dependent on the maximum operating junction temperature (T
J(max)
), the
maximum power dissipation of the device in the application (P
D(max)
), and the junction-to-ambient thermal resistance of the part/package
in the application ( θ
JA
), as given by the following equation: T
A(max)
= T
J(max)
–( θ
JA
X P
D(max)
).
(4) The human body model is a 100-pF capacitor discharged through a 1.5-k Ω resistor into each pin. The machine model is a 200-pF
capacitor discharged directly into each pin.
