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) VIN Pin −0.3V to +8V En Pin −0.3V to +8V Fb Pin −0.3V to +8V Sw2 Pin −0.3V to +8V Ovp Pin −0.3V to +30V Sw1 Pin −0.3V to +40V Continuous Power Dissipation Internally Limited Maximum Junction Temperature (TJ-MAX) +150°C Storage Temperature Range −65°C to +150°C ESD Rating (3) Human Body Model 2 kV Machine Model 150V (1) Absolute maximum ratings indicate limits beyond which damage to the device may occur. Electrical characteristic specifications do not apply when operating the device outside of its rated operating conditions. (2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office / Distributors for availability and specifications. (3) 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. 2 Submit Documentation Feedback Copyright © 2004–2013, Texas Instruments Incorporated Product Folder Links: LM3557 |
