4 / 44 page LM1575, LM2575-N, LM2575HV SNVS106E – MAY 1999 – REVISED APRIL 2013 www.ti.com These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. ABSOLUTE MAXIMUM RATINGS (1) (2) (3) Maximum Supply Voltage LM1575/LM2575 45V LM2575HV 63V ON /OFF Pin Input Voltage −0.3V ≤ V ≤ +VIN Output Voltage to Ground (Steady State) −1V Power Dissipation Internally Limited Storage Temperature Range −65°C to +150°C Maximum Junction Temperature 150°C Minimum ESD Rating (C = 100 pF, R = 1.5 k Ω) 2 kV Lead Temperature (Soldering, 10 sec.) 260°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 ensure specific performance limits. For specified specifications and test conditions, see Electrical Characteristics. (2) If Military/Aerospace specified devices are required, please contact the TI Sales Office/ Distributors for availability and specifications. (3) Refer to RETS LM1575J for current revision of military RETS/SMD. OPERATING RATINGS Temperature Range LM1575 −55°C ≤ TJ ≤ +150°C LM2575/LM2575HV −40°C ≤ TJ ≤ +125°C Supply Voltage LM1575/LM2575 40V LM2575HV 60V ELECTRICAL CHARACTERISTICS LM1575-3.3, LM2575-3.3, LM2575HV-3.3 Specifications with standard type face are for TJ = 25°C, and those with boldface type apply over full Operating Temperature Range .

All limits are used to calculate Average Outgoing Quality Level, and all are 100% production tested. (2) All limits specified at room temperature (standard type face) and at temperature extremes (bold type face). All room temperature limits are 100% production tested. All limits at temperature extremes are specified via correlation using standard Statistical Quality Control (SQC) methods. (3) External components such as the catch diode, inductor, input and output capacitors can affect switching regulator system performance. When the LM1575/LM2575 is used as shown in the test circuit Figure 25 and Figure 26, system performance will be as shown in system parameters of Electrical Characteristics. 4 Submit Documentation Feedback Copyright © 1999–2013, Texas Instruments Incorporated Product Folder Links: LM1575 LM2575-N LM2575HV |
