3 / 29 page LM20123 www.ti.com SNVS524E – OCTOBER 2007 – REVISED MARCH 2013 ABSOLUTE MAXIMUM RATINGS (1) Voltages from the indicated pins to GND AVIN, PVIN, EN, PGOOD, SS/TRK, COMP, FB, SW -0.3V to +6V Storage Temperature -65°C to 150°C Junction Temperature 150°C Power Dissipation(2) 2.6W Lead Temperature (Soldering, 10 sec) 260°C Minimum ESD Rating(3) ±2kV (1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is intended to be functional, but do not specific performance limits. For specifications and test conditions, see the Electrical Characteristics. (2) The maximum allowable power dissipation is a function of the maximum junction temperature, TJ_MAX, the junctions-to-ambient thermal resistance, θJA, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated using: PD_MAX = (TJ_MAX – TA)/θJA. The maximum power dissipations of 2.6W is determined using TA = 25°C, θJA = 38°C/W, and TJ_MAX = 125°C. (3) The human body model is a 100 pF capacitor discharged through a 1.5 k Ω resistor to each pin.
