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) The YFF package is available in tape on reel. Add R suffix (TPS61240YFFR) to order quantities of 3000 parts per reel. Add a T suffix
(TPS61240YFFT) to order quantities of 250 parts.
(2) Contact TI for other fixed output voltage options.

(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) The human body model is a 100pF capacitor discharged through a 1.5 kΩ resistor into each pin. The machine model is a 200pF
capacitor discharged directly into each pin.

(1) Maximum power dissipation is a function of TJ(max), θJA and TA. The maximum allowable power dissipation at
any allowable ambient temperature is PD = [TJ(max)-TA] / θJA.
(2) This thermal data is measured with high-K board (4 layer board according to JESD51-7 JEDEC standard).
