3 / 37 page LM3550 www.ti.com SNVS569B – MAY 2009 – REVISED MAY 2013 Absolute Maximum Ratings (1) (2) (3) VIN to GND −0.3V to 6V VOUT, LED−, FB to GND −0.3V to 6V SDA, SCL, STROBE, FET_CON, EOC, ALD/TEMP, IND to GND −0.3V to 6V Continuous Power Dissipation(4) Internally Limited Junction Temperature (TJ-MAX ) 150°C Storage Temperature Range −65°C to +150 Maximum Lead Temperature (Soldering, 10s) See(5) ESD Rating(6) Human Body Model 2 kV Machine Model(7) 200V (1) Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under which operation of the device is ensured. Operating Ratings do not imply ensured performance limits. For ensured performance limits and associated test conditions, see the Electrical Characteristics tables. (2) All voltages are with respect to the potential at the GND pin. (3) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and specifications. (4) Internal thermal shutdown circuitry protects the device from permanent damage. Thermal shutdown engages at TJ = 145ºC (typ.) and disengages at TJ = 125ºC (typ.). The thermal shutdown is specified by design. (5) For detailed soldering specifications and information, please refer to Texas Instruments Application Note: AN-1187 (SNOA401) for Recommended Soldering Profiles. (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 through a 0 Ω (nominal) resistor into each pin.(MIL-STD-883 3015.7). Texas Instruments recommends that all integrated circuits be handled with appropriate ESD precautions. Failure to observe proper ESD handling techniques can result in damage to the device. (7) The LED − pin has a machine model ESD rating of 150V. Operating Ratings (1) (2) Input Voltage Range 2.7V to 5.5V Junction Temperature Range −30°C to 125°C (TJ) (3) Ambient Temperature Range −30°C to +85°C (TA) (4) (1) Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under which operation of the device is ensured. Operating Ratings do not imply ensured performance limits.

Texas Instruments recommends that all integrated circuits be handled with appropriate ESD precautions. Failure to observe proper ESD handling techniques can result in damage to the device. Thermal Properties Junction-to-Ambient Thermal Resistance ( θJA) (1) 57°C/W (1) 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-OP = 125ºC), 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-OP – (θJA × PD-MAX).
