3 / 31 page  LM25085A www.ti.com SNVS601B – JANUARY 2009 – REVISED MARCH 2013 Absolute Maximum Ratings (1) (2) VIN to GND -0.3V to 45V ISEN to GND -0.3V to VIN + 0.3V ADJ to GND -0.3V to VIN + 0.3V RT, FB to GND -0.3V to 7V VIN to VCC, VIN to PGATE -0.3V to 10V ESD Rating (3) Human Body Model 2kV Storage Temperature Range -65°C to +150°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. (2) If Military/Aerospace specified devices are required, please contact the TI Sales Office/ Distributors for availability and specifications. (3) The human body model is a 100 pF capacitor discharged through a 1.5 k Ω resistor into each pin. Operating Ratings (1) VIN Voltage 4.5V to 42V Junction Temperature −40°C to + 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. 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 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 = 24V, RT = 100 kΩ.
