4 / 29 page  LMZ14203 SNVS632R – DECEMBER 2009 – REVISED OCTOBER 2015 www.ti.com 6.2 ESD Ratings VALUE UNIT V(ESD) Electrostatic discharge Human body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±2000 V (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. 6.3 Recommended Operating Conditions over operating free-air temperature range (unless otherwise noted) (1) MIN MAX UNIT VIN 6 42 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. Recommended Operating Ratings are conditions under which operation of the device is intended to be functional. For ensured specifications and test conditions, see the Electrical Characteristics. 6.4 Thermal Information LMZ14203 THERMAL METRIC(1) NDW (TO-PMOD) UNIT 7 PINS 4-layer JEDEC Printed Circuit Board, No air flow 19.3 Junction-to-ambient RθJA °C/W thermal resistance 2-layer JEDEC Printed Circuit Board, No air flow 21.5 Junction-to-case (top) RθJC(top) No air flow 1.9 °C/W thermal resistance (1) For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics application report, SPRA953. 6.5 Electrical Characteristics Limits in standard type are for TJ = 25°C only; limits in boldface type apply over the junction temperature (TJ) range of –40°C to +125°C. Minimum and Maximum limits are ensured 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 = 24 V, Vout = 3.3 V PARAMETER TEST CONDITIONS MIN(1) TYP(2) MAX(1) UNIT SYSTEM PARAMETERS Enable Control(3) VEN EN threshold trip VEN rising 1.18 point V over the junction temperature (TJ) 1.1 1.25 range of –40°C to +125°C VEN-HYS EN threshold VEN falling 90 mV hysteresis Soft-Start ISS SS source current VSS = 0V 8 µA over the junction temperature (TJ) 5 11 range of –40°C to +125°C ISS-DIS SS discharge –200 µA current Current Limit ICL Current limit DC average 4.2 threshold VIN= 12 V to 24 V A over the junction temperature (TJ) 3.2 5.25 range of –40°C to +125°C (1) Minimum and Maximum limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlation using Statistical Quality Control (SQC) methods. Limits are used to calculate Average Outgoing Quality Level (AOQL). (2) Typical numbers are at 25°C and represent the most likely parametric norm. (3) EN 55022:2006, +A1:2007, FCC Part 15 Subpart B: 2007.
