8.1 Absolute Maximum Ratings
over operating free-air temperature range (unless otherwise noted)(1)| MIN | MAX | UNIT | ||
|---|---|---|---|---|
| VIN | Input voltage range on VIN, L, VAUX, VOUT, PS, EN, FB, UVLO | –0.3 | 7 | V |
| TJ | Operating junction temperature | –40 | 150 | °C |
| Tstg | Storage temperature | –65 | 150 | °C |
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
8.2 ESD Ratings
| VALUE | UNIT | |||
|---|---|---|---|---|
| V(ESD) | Electrostatic discharge | Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) | ±4000 | V |
| Charged-device model (CDM), per JEDEC specification JESD22-C101(2) | ±1500 | |||
| Machine Model (MM)(3) | ±200 | |||
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 500-V HBM is possible with the necessary precautions.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 250-V CDM is possible with the necessary precautions.
(3) ESD testing is performed according to the respective JESD22 JEDEC standard.
8.3 Recommended Operating Conditions
