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. (2) The maximum voltage that can be applied to these pins is 30 V or PVIN, whichever is less. (3) See temperature derating curves in the Typical Characteristics section for thermal information. 6 Specifications 6.1 Absolute Maximum Ratings over operating free-air temperature range (unless otherwise noted) (1) MIN MAX UNIT Input voltage PVIN, INH/UVLO –0.3 50 V VOUT, SENSE+, VBSEL –0.3 30(2) V VADJ, VERSA-COMP, RT, RTSEL, SS/TR –0.3 3.6 V PWRGD, PWRGD_PU –0.3 15 V CLK –0.3 5.5 V Output voltage PH –0.3 50 V Operating junction temperature(3) –40 125 °C Mechanical shock Mil-STD-883D, Method 2002.3, 1 msec, 1/2 sine, mounted 1500 G Mechanical vibration Mil-STD-883D, Method 2007.2, 20-2000Hz 20 G Storage temperature, Tstg –65 150 °C (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. 6.2 ESD Ratings VALUE UNIT V(ESD) Electrostatic discharge Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±1000 V Charged-device model (CDM), per JEDEC specification JESD22-C101(2) ±1000 6.3 Recommended Operating Conditions over operating free-air temperature range (unless otherwise noted) MIN NOM MAX UNIT PVIN Input voltage 4.5 42 V VOUT Output voltage 2.5 7.5 V ƒSW Switching frequency 300 1000 kHz TA Operating ambient temperature –40 105 °C (1) For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics application report, SPRA953. 6.4 Thermal Information THERMAL METRIC(1) LMZ34202 UNIT RVQ (QFN) 43 PINS RθJA Junction-to-ambient thermal resistance 14 °C/W ψJT Junction-to-top characterization parameter 2.6 °C/W ψJB Junction-to-board characterization parameter 9 °C/W |
