(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 specific performance is not ensured. For specific specifications and the test conditions,  
see Electrical Characteristics.  
(2) Thermal shutdown will occur if the junction temperature exceeds 165°C. The maximum power dissipation is a function of TJ(MAX) , θJA  
and TA . The maximum allowable power dissipation at any ambient temperature is PD = (TJ(MAX) – TA)/θJA . All numbers apply for  
packages soldered directly onto a 3” x 3” PC board with 2oz. copper on 4 layers in still air. For a 2 layer board using 1 oz. copper in still  
air, θJA = 204°C/W.  
Electrical Characteristics  
Specifications with standard typeface are for TJ = 25°C, and those in boldface type apply over the full Operating  
Temperature Range (TJ = -40°C to 125°C). VIN = 5V, VBOOST - VSW = 5V unless otherwise specified. Datasheet min/max  
specification limits are ensured by design, test, or statistical analysis.
