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.

Internal tap points are available to facilitate output voltages in 25mV increments.
(3)
The YFD package is available in tape and reel. Add a R suffix (e.g. TPS62692YFDR) to order quantities of 3000 parts. Add a T suffix
(e.g. TPS62692YFDT) to order quantities of 250 parts.

(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)
Operation above 4.8V input voltage is not recommended over an extended period of time.
(3)
All voltage values are with respect to network ground terminal.
(4)
Limited to 50% Duty Cycle over Lifetime.
(5)
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 (TA(max)) is dependent on the maximum operating junction temperature (TJ(max)), the
maximum power dissipation of the device in the application (PD(max)), and the junction-to-ambient thermal resistance of the part/package
in the application (
θJA), as given by the following equation: TA(max)= TJ(max)–(θJA X PD(max)). To achieve optimum performance, it is
recommended to operate the device with a maximum junction temperature of 105°C.
(6)
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.
