7.1 Absolute Maximum Ratings
over operating free-air temperature range (unless otherwise noted)(1)| MIN | MAX | UNIT | ||
|---|---|---|---|---|
| Supply voltage on pin VIN(2) | –0.3 | 7 | V | |
| Voltage on pins CP2, EN, and SS(2) | –0.3 | 7 | V | |
| Voltage on pin CP1 and FB(2) | –0.3 | 3 | V | |
| Voltage on pin SW, VO, and OUT(2) | –0.3 | 20 | V | |
| Operating Junction Temperature Range | -40 | 150 | °C | |
| Tstg, Storage temperature range | -55 | 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.
(2) All voltage values are with respect to network ground terminal.
7.2 ESD Ratings
| VALUE | UNIT | |||||
|---|---|---|---|---|---|---|
| V(ESD) | Electrostatic discharge | Human body model (HBM), per AEC Q100-002(1) | ±2000 | V | ||
| Charged device model (CDM), per AEC Q100-011 |
Corner pins (1, 5, 6, and 10) | ±750 | ||||
| Other pins | ±500 | |||||
(1) AEC Q100-002 indicates HBM stressing is done in accordance with the ANSI/ESDA/JEDEC JS-001 specification.
