5 / 40 page LM10520 www.ti.com SNVS638 – NOVEMBER 2010 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. ABSOLUTE MAXIMUM RATINGS (1) (2) ON/OFF, VIN -0.3V to 16V VCC -0.3V to 6V LG, PGND, SGND, PWGD, HG, SD, FB, SS/TRACK, EAO, FREQ/SYNC -0.3V to VCC + 0.3V BOOT -0.3V to 18V ISEN -0.3V to 14V VPWI -0.2V to VDD SPWI, SCLK -0.2 to VPWI All other pins -0.2V to 6V Junction Temperature 150°C Storage Temperature -45°C to 150°C ESD Tolerance (3) Human Body Model 1.5 kV Soldering Information See product folder at www.ti.com and literature number SNOA549 (1) Absolute maximum ratings indicate limits beyond which damage to the device may occur. Operating ratings indicate conditions for which the device operates correctly. Operating Ratings do not imply ensured performance limits. (2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and specifications. (3) ESD using the human body model which is a 100 pF capacitor discharged through a 1.5 k Ω resistor into each pin. OPERATING RATINGS VIN 3.5V to 16V VCC, VDD 3V to 5.5V VPWI(1) 1.6V to 3.6V BOOT Voltage 1V to 17V Junction Temperature -40°C to 125°C (1) Note: VPWI cannot be higher than VDD THERMAL PROPERTIES Junction-to-Ambient Thermal Resistance 26°C/W ELECTRICAL CHARACTERISTICS VCC = 3.3V unless otherwise indicated. Typicals and limits appearing in plain type apply for TA= TJ= 25°C. Limits appearing in boldface type apply over full Operating Temperature Range. Datasheet min/max specification limits are specified by design, test, or statistical analysis.
