7.1 Absolute Maximum Ratings
TJ = -40°C to 150°C (unless otherwise noted) (1)| MIN | MAX | UNIT | ||
|---|---|---|---|---|
| Input voltage range | VIN, EN | –0.3 | 19 | V |
| VBST | –0.3 | 25 | V | |
| VBST (10 ns transient) | –0.3 | 27.5 | V | |
| VBST (vs SW) | –0.3 | 6.5 | V | |
| VFB, PG | –0.3 | 6.5 | V | |
| SS | –0.3 | 5.5 | V | |
| SW | –2 | 19 | V | |
| SW (10 ns transient) | –3.5 | 21 | V | |
| Operating junction temperature, TJ | –40 | 150 | °C | |
| Storage temperature, Tstg | –55 | 150 | °C | |
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. 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.
7.2 ESD Ratings
| VALUE | UNIT | |||
|---|---|---|---|---|
| V(ESD) | Electrostatic discharge | Human body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) | ±2000 | V |
| Charged device model (CDM), per JEDEC specification JESD22-C101(2) | ±500 | V | ||
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
