4 / 31 page LMZ23610 SNVS707C – MARCH 2011 – REVISED MAY 2011 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) VIN to PGND -0.3V to 40V EN, SYNC to AGND -0.3V to 5.5V SS, FB, SH to AGND -0.3V to 2.5V AGND to PGND -0.3V to 0.3V Junction Temperature 150°C Storage Temperature Range -65°C to 150°C ESD Susceptibility (3) ± 2 kV For soldering specifications: see product folder at www.ti.com and literature number SNOA549 (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 ensured specifications and test conditions, see the Electrical Characteristics. (2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and specifications. (3) The human body model is a 100pF capacitor discharged through a 1.5 k Ω resistor into each pin. Test method is per JESD-22-114. OPERATING RATINGS (1) VIN 6V to 36V EN, SYNC 0V to 5.0V Operation 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 ensured 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 = 12V, VOUT = 3.3V Min Typ Max Symbol Parameter Conditions Units (1) (2) (1) SYSTEM PARAMETERS Enable Control VEN EN threshold VEN rising 1.096 1.274 1.452 V IEN-HYS EN hysteresis source current VEN > 1.274V 13 µA Soft-Start ISS SS source current VSS = 0V 40 50 60 µA tSS Internal soft-start interval 1.6 msec Current Limit ICL Current limit threshold d.c. average 12.5 A Internal Switching Oscillator fosc Free-running oscillator frequency Sync input connected to ground 314 359 404 kHz fsync Synchronization range Vsync = 3.3Vp-p 314 600 kHz VIL-sync Synchronization logic zero Relative to AGND 0.4 V amplitude VIH-sync Synchronization logic one Relative to AGND 1.8 V amplitude Sync d.c. Synchronization duty cycle range 15 50 85 % (1) Min and Max limits are 100% production tested at 25°C. Limits over the operating temperature range are specified through correlation using Statistical Quality Control (SQC) methods. Limits are used to calculate TI’s Average Outgoing Quality Level (AOQL). (2) Typical numbers are at 25°C and represent the most likely parametric norm. 4 Submit Documentation Feedback Copyright © 2011, Texas Instruments Incorporated Product Folder Links: LMZ23610 |
