4 / 27 page LM2775 SNVSA57 – MAY 2015 www.ti.com 6 Specifications 6.1 Absolute Maximum Ratings over operating free-air temperature range (unless otherwise noted) (1) MIN MAX UNIT VIN, VOUT –0.3 6 V EN, OUTDIS, PFM –0.3 VIN + 0.3 with 6 V Max V Continuous power dissipation Internally Limited °C Junction temperature (TJ-MAX) 125 °C Storage temperature, Tstg –65 150 °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. 6.2 ESD Ratings VALUE UNIT Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±1000 Electrostatic V(ESD) V discharge Charged-device model (CDM), per JEDEC specification JESD22-C101(2) ±250 (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. 6.3 Recommended Operating Conditions over operating free-air temperature range (unless otherwise noted) MIN NOM MAX UNIT VIN 2.7 5.5 V Junction temperature (TJ ) –40 125 °C Ambient temperature (TA ) –40 85 °C 6.4 Thermal Information LM2775 THERMAL METRIC(1) DSG (WSON) UNIT 8 PINS RθJA Junction-to-ambient thermal resistance 71.6 RθJC(top) Junction-to-case (top) thermal resistance 95.0 RθJB Junction-to-board thermal resistance 41.5 °C/W ψJT Junction-to-top characterization parameter 3.2 ψJB Junction-to-board characterization parameter 41.8 RθJC(bot) Junction-to-case (bottom) thermal resistance 12.8 (1) For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report, SPRA953. 4 Submit Documentation Feedback Copyright © 2015, Texas Instruments Incorporated Product Folder Links: LM2775 |
