4 / 58 page LM25066A SNVS700F – DECEMBER 2010 – REVISED FEBRUARY 2013 www.ti.com Absolute Maximum Ratings (1) VIN, SENSE to GND (2) -0.3V to 24V GATE, FB, UVLO/EN, OVLO, PGD to GND (2) -0.3V to 20V OUT to GND -1V to 20V SCL, SDA, SMBA, CL, CB, ADR0, ADR1, ADR2, VDD, VAUX, DIODE, RETRY to GND -0.3V to 6V VIN to SENSE -0.3V to +0.3V ESD Rating, Human Body Model(3) 2kV Storage Temperature -65°C to +150°C Junction Temperature +150°C (1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and conditions, see the Electrical Characteristics. (2) The GATE pin voltage is typically 7.5V above VIN when the LM25066A is enabled. Therefore the Absolute Maximum Rating of 24V for VIN and SENSE apply only when the LM25066A is disabled or for a momentary surge to that voltage since the Absolute Maximum Rating of the GATE pin is 20V. (3) The human body model is a 100 pF capacitor discharged through a 1.5 k Ω resistor into each pin. Operating Ratings VIN, SENSE, OUT voltage 2.9V to 17V VDD 2.9V to 5.5V Junction Temperature −40°C to +125°C 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 +85°C unless otherwise stated. Minimum and Maximum limits are guaranteed 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 = 12V.

(2) All limits are guaranteed. All electrical characteristics having room temperature limits are tested during production at TA = 25°C. All hot and cold limits are guaranteed by correlating the electrical characteristics to process and temperature variations and applying statistical process control. 4 Submit Documentation Feedback Copyright © 2010–2013, Texas Instruments Incorporated Product Folder Links: LM25066A |
