TJ (3) 150°C Lead Temperature (Soldering 10 sec.) 300°C Vapor Phase (60 sec.) 215°C Infrared (15 sec.) 220°C ESD Ratings (4) Human Body Model 2kV Machine Model (5) 200V (1) Absolute maximum ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions for which the device is intended to be functional, but device parameter specifications may not be ensured. For ensured specifications and test conditions, see the Electrical Characteristics. (2) If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications. (3) The maximum allowable power dissipation is a function of the maximum junction temperature, TJ(MAX), the junction-to-ambient thermal resistance, θJA, and the ambient temperature, TA. See the Electrical Characteristics table for the thermal resistance. The maximum allowable power dissipation at any ambient temperature is calculated using: PD (MAX) = (TJ(MAX) − TA)/θJA. Exceeding the maximum allowable power dissipation will cause excessive die temperature. (4) 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. (5) ESD susceptibility using the machine model is 150V for SW pin. Operating Conditions Junction Temperature (1) −40°C to +125°C Supply Voltage 2.2V to 7V SW Voltage Max. 22V (1) All limits ensured at room temperature and at temperature extremes. All room temperature limits are 100% production tested or ensured through statistical analysis. All limits at temperature extremes are ensured via correlation using standard Statistical Quality Control (SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL). Electrical Characteristics Specifications in standard type face are for TJ = 25°C and those in boldface type apply over the full Operating Temperature Range (TJ = −40°C to +125°C). Unless otherwise specified. VIN =2.2V.

All room temperature limits are 100% production tested or ensured through statistical analysis. All limits at temperature extremes are ensured via correlation using standard Statistical Quality Control (SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL). (2) Typical numbers are at 25°C and represent the most likely norm. (3) Feedback current flows into the pin.
