4 / 33 page LM5060 SNVS628F – OCTOBER 2009 – REVISED APRIL 2013 www.ti.com Electrical Characteristics Unless otherwise stated the following conditions apply: VIN = 14V, EN =2.00V, UVLO =2.00V, OVP = 1.50V, and TJ = 25°C. Limits in standard type are for TJ = 25°C only; limits in boldface type apply over the operating 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.

Therefore, the Absolute Maximum Rating for VIN (75V) applies only when the LM5060 is disabled, or for a momentary surge to that voltage since the Absolute Maximum Rating for the GATE pin is also 75V. 4 Submit Documentation Feedback Copyright © 2009–2013, Texas Instruments Incorporated Product Folder Links: LM5060 |
