4 / 31 page LMZ12002 SNVS650H – JANUARY 2010 – REVISED AUGUST 2015 www.ti.com 6.3 Recommended Operating Conditions (1) over operating free-air temperature range (unless otherwise noted) MIN MAX UNIT VIN 4.5 20 V EN 0 6.5 V Operation Junction Temperature –40 125 °C (1) Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the device is intended to be functional. For specifications and test conditions, see the Electrical Characteristics. 6.4 Thermal Information LMZ12002 THERMAL METRIC(1) NDW UNIT 7 PINS RθJA 4-layer JEDEC Printed-Circuit-Board, 100 19.3 vias, No air flow Junction-to-ambient thermal resistance (2) °C/W 2-layer JEDEC Printed-Circuit-Board, No 21.5 air flow RθJC(top) Junction-to-case (top) thermal resistance No air flow 1.9 °C/W (1) For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report, SPRA953. (2) RθJA measured on a 1.705-in × 3.0-in 4-layer board, with 1-oz. copper, thirty five thermal vias, no air flow, and 1-W power dissipation. Refer to PCB layout diagrams. 6.5 Electrical Characteristics Limits are for TJ = 25°C unless otherwise specified. Minimum and Maximum limits are specified through test, design or statistical correlation. Typical values represent the most likely parametric norm at TJ = 25°C, and are provided for reference purposes only. Unless otherwise stated the following conditions apply: VIN = 12 V, VOUT = 1.8 V (1). PARAMETER TEST CONDITIONS MIN(2) TYP(3) MAX(2) UNIT SYSTEM PARAMETERS ENABLE CONTROL 1.18 VEN EN threshold trip point VEN rising V over the junction temperature 1.1 1.25 (TJ) range of -40°C to +125°C VEN-HYS EN threshold hysteresis VEN falling 90 mV SOFT-START 8 ISS SS source current VSS = 0 V µA over the junction temperature 5 11 (TJ) range of -40°C to +125°C ISS-DIS SS discharge current –200 µA CURRENT LIMIT 2.6 ICL Current limit threshold DC average A over the junction temperature 2.3 3.65 (TJ) range of -40°C to +125°C ON/OFF TIMER ON timer minimum pulse tON-MIN 150 ns width tOFF OFF timer pulse width 260 ns (1) EN 55022:2006, +A1:2007, FCC Part 15 Subpart B: 2007. See AN-2024 and layout for information on device under test. (2) Minimum and Maximum limits are 100% production tested at 25°C. Limits over the operating temperature range are specified through correlation using Statistical Quality Control (SQC) methods. Limits are used to calculate Average Outgoing Quality Level (AOQL). (3) Typical numbers are at 25°C and represent the most likely parametric norm. 4 Submit Documentation Feedback Copyright © 2010–2015, Texas Instruments Incorporated Product Folder Links: LMZ12002 |
