7.1 Absolute Maximum Ratings
over operating free-air temperature range (unless otherwise noted)(1)| MIN | MAX | UNIT | ||
|---|---|---|---|---|
| Input voltage on LBI | –0.3 | 3.6 | V | |
| Input voltage on SW, VOUT, LBO, VBAT, SYNC, EN, FB | –0.3 | 7 | V | |
| TA | Operating free air temperature | –40 | 85 | °C |
| TJ | Maximum junction temperature | 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.
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) | ±1000 | |||
(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. Pins listed as ±XXX V may actually have higher performance.
(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. Pins listed as ±YYY V may actually have higher performance.
7.3 Recommended Operating Conditions
| MIN | NOM | MAX | UNIT | ||
|---|---|---|---|---|---|
| VI | Supply voltage at VBAT | 1.8 | 5.5 | V | |
| L | Inductance | 2.2 | 6.8 | µH | |
| Ci | Input, capacitance | 10 | µF | ||
| Co | Output capacitance | 22 | 100 | ||
| TA | Operating free air temperature | –40 | 85 | °C | |
| TJ | Operating virtual junction temperature | –40 | 125 |
