4 / 26 page TPS54325 SLVS932F – MAY 2009 – REVISED NOVEMBER 2014 www.ti.com 7 Specifications 7.1 Absolute Maximum Ratings over operating free-air temperature range (unless otherwise noted) (1) MIN MAX UNIT VIN, VCC, EN –0.3 20 V VBST –0.3 26 V VBST (vs SW1, SW2) –0.3 6.5 V VI Input voltage range VFB, VO, SS, PG –0.3 6.5 V SW1, SW2 –2 20 V SW1, SW2 (10 ns transient) –3 20 V VREG5 –0.3 6.5 V VO Output voltage range PGND1, PGND2 –0.3 0.3 V Vdiff Voltage from GND to POWERPAD –0.2 0.2 V TJ Operating junction temperature –40 150 °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 Handling Ratings MIN MAX UNIT Tstg Storage temperature range –55 150 °C Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all 2000 pins(1) V(ESD) Electrostatic discharge V Charged device model (CDM), per JEDEC specification JESD22- 500 C101, all pins(2) (1) JEDEC document JEP155 states that 2000-V HBM allows safe manufacturing with a standard ESD control process. (2) JEDEC document JEP157 states that 500-V CDM allows safe manufacturing with a standard ESD control process. 7.3 Thermal Information PWP THERMAL METRIC(1) UNIT 12 PINS RθJA Junction-to-ambient thermal resistance 55.6 RθJC(top) Junction-to-case (top) thermal resistance 51.3 RθJB Junction-to-board thermal resistance 26.4 °C/W ψJT Junction-to-top characterization parameter 1.8 ψJB Junction-to-board characterization parameter 20.6 RθJC(bot) Junction-to-case (bottom) thermal resistance 4.3 (1) For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report, SPRA953. 4 Submit Documentation Feedback Copyright © 2009–2014, Texas Instruments Incorporated Product Folder Links: TPS54325 |
