2 / 28 page LM2591HV SNVS074D – MAY 2001 – 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) Maximum Supply Voltage (VIN) 63V ON/OFF Pin Voltage −0.3 ≤ V ≤ +25V Feedback Pin Voltage −0.3 ≤ V ≤ +25V Output Voltage to Ground (Steady State) −1V Power Dissipation Internally limited Storage Temperature Range −65°C to +150°C ESD Susceptibility Human Body Model (3) 2 kV Lead Temperature KTT Package Vapor Phase (60 sec.) +215°C Infrared (10 sec.) +245°C NDH Package (Soldering, 10 sec.) +260°C Maximum 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 ensure specific performance limits. For ensured 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) The human body model is a 100 pF capacitor discharged through a 1.5k resistor into each pin. OPERATING CONDITIONS Temperature Range −40°C ≤ TJ ≤ +125°C Supply Voltage 4.5V to 60V ELECTRICAL CHARACTERISTICS LM2591HV-3.3 Specifications with standard type face are for TJ = 25°C, and those with boldface type apply over full Operating Temperature Range. Symbol Parameter Conditions LM2591HV-3.3 Units (Limits) Typ (1) Limit (2) SYSTEM PARAMETERS Test Circuit Test Circuit and Layout Guidelines(3) VOUT Output Voltage 4.75V ≤ VIN ≤ 60V, 0.2A ≤ ILOAD ≤ 1A 3.3 V 3.168/3.135 V(min) 3.432/3.465 V(max) η Efficiency VIN = 12V, ILOAD = 1A 77 (1) Typical numbers are at 25°C and represent the most likely norm. (2) All limits ensured 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 ensured via correlation using standard Statistical Quality Control (SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL). (3) External components such as the catch diode, inductor, input and output capacitors can affect switching regulator system performance. When the LM2591HV is used as shown in Test Circuit and Layout Guidelines test circuit, system performance will be as shown in Electrical Characteristics. 2 Submit Documentation Feedback Copyright © 2001–2013, Texas Instruments Incorporated Product Folder Links: LM2591HV |
