8 Specifications
8.1 Absolute Maximum Ratings
over operating free-air temperature range (unless otherwise noted)(1)| MIN | MAX | UNIT | ||
|---|---|---|---|---|
| Voltage(2) | VIN, VOUT, SW, EN, PG, FB, ILIM | –0.3 | 7 | V |
| Temperature | Operating junction, TJ | –40 | 150 | °C |
| Storage, Tstg | –65 | 150 | ||
(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 my affect device reliability.
(2) All voltages are with respect to network ground terminal.
8.2 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 | |||
(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.
8.3 Recommended Operating Conditions
| MIN | NOM | MAX | UNIT | |
|---|---|---|---|---|
| Supply voltage at VIN | 2.3 | 6.0 | V | |
| Output voltage at VOUT | 3.0 | 6.5 | V | |
| Programmable valley switch current limit set by RILIM | 100 | 1500 | mA | |
| Operating free air temperature range, TA | –40 | 85 | °C | |
| Operating junction temperature range, TJ | –40 | 125 | °C |
8.4 Thermal Information
| THERMAL METRIC(1) | TPS61252 | UNIT | |
|---|---|---|---|
| DSG | |||
| 8 PINS | |||
| RθJA | Junction-to-ambient thermal resistance | 80.2 | °C/W |
| RθJC(top) | Junction-to-case (top) thermal resistance | 93.5 | |
| RθJB | Junction-to-board thermal resistance | 54.2 | |
| ψJT | Junction-to-top characterization parameter | 0.9 | |
| ψJB | Junction-to-board characterization parameter | 59.3 | |
| RθJC(bot) | Junction-to-case (bottom) thermal resistance | 20 | |
