2 / 23 page TPS7A49xx SBVS121B – AUGUST 2010 – REVISED JANUARY 2010 www.ti.com This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. ORDERING INFORMATION(1) PRODUCT VOUT TPS7A49xx yyy z XX is nominal output voltage (01 = Adjustable).(2) YYY is package designator. Z is package quantity. (1) For the most current package and ordering information see the Package Option Addendum at the end of this document, or visit the device product folder on www.ti.com. (2) For fixed -1.2V operation, tie FB to OUT. ABSOLUTE MAXIMUM RATINGS (1) Over operating free-air temperature range (unless otherwise noted). VALUE MIN MAX UNIT IN pin to GND pin –0.3 +36 V OUT pin to GND pin –0.3 +33 V OUT pin to IN pin –36 +0.3 V FB pin to GND pin –0.3 +2 V Voltage FB pin to IN pin –36 +0.3 V EN pin to IN pin –36 0.3 EN pin to GND pin –0.3 +36 V NR/SS pin to IN pin –36 +0.3 V NR/SS pin to GND pin –0.3 +2 V Current Peak output Internally limited Operating virtual junction, TJ –40 +125 °C Temperature Storage, Tstg –65 +150 °C Human body model (HBM) 1500 V Electrostatic discharge rating Charged device model (CDM) 500 V (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 is not implied. Exposure to absolute-maximum rated conditions for extended periods may affect device reliability. THERMAL INFORMATION TPS7A49xx THERMAL METRIC(1) DGN UNITS 8 PINS qJA Junction-to-ambient thermal resistance 55.09 qJC(top) Junction-to-case(top) thermal resistance 8.47 qJB Junction-to-board thermal resistance — °C/W yJT Junction-to-top characterization parameter 0.36 yJB Junction-to-board characterization parameter 14.6 qJC(bottom) Junction-to-case(bottom) thermal resistance — (1) For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report, SPRA953. DISSIPATION RATINGS DERATING FACTOR TA ≤ +25°C POWER TA = +70°C POWER TA = +85°C POWER BOARD PACKAGE RqJA RqJC ABOVE TA = +25°C RATING RATING RATING High-K(1) DGN 55.9°C/W 8.47°C/W 16.6mW/°C 1.83W 1.08W 0.833W (1) The JEDEC High-K (2s2p) board design used to derive this data was a 3-inch x 3-inch multilayer board with 2-ounce internal power and ground planes and 2-ounce copper traces on top and bottom of the board. 2 Submit Documentation Feedback Copyright © 2010, Texas Instruments Incorporated |
