These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and specifications. (3) The absolute maximum specification of the Switch Voltage to Ground applies to DC voltage. An extended negative voltage limit of –10 V applies to a pulse of up to 20 ns, –6 V of 60 ns and –3 V of up to 100 ns. 6 Specifications 6.1 Absolute Maximum Ratings (1) (2) MIN MAX UNIT Input supply voltage 45 V Soft-start pin voltage –0.1 6 V Switch voltage to ground(3) –1 VIN V Boost pin voltage VSW + 8 V V Feedback pin voltage –0.3 14 V Power dissipation Internally Limited Soldering temperature Wave, 4 s 260 °C Infrared, 10 s 240 Vapor phase, 75 s 219 Storage temperature, Tstg –65 150 °C (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. (2) ESD was applied using the human-body model, a 100-pF capacitor discharged through a 1.5-kΩ resistor into each pin. 6.2 ESD Ratings VALUE UNIT V(ESD) Electrostatic discharge Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1)(2) ±2000 V 6.3 Recommended Operating Conditions MIN MAX UNIT Supply voltage 8 40 V Junction temperature (TJ) –40 125 °C |
