2 / 41 page ABSOLUTE MAXIMUM RATINGS (1) DISSIPATION RATINGS (1) TPS51427 SLUS819A – APRIL 2008 – REVISED MAY 2008 .............................................................................................................................................................. 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. ORDERING INFORMATION(1) ORDERABLE TA PACKAGE PART NO. TRANSPORT MEDIA QUANTITY ECO STATUS(2) TPS51427RHBT 250 Green Plastic Quad Flatpack –40 °C to +85°C Tape and Reel (RoHs and No (32-pin QFN) TPS51427RHBR 3000 Sb/Br) (1) For the most current package and ordering information see the Package Option Addendum at the end of this document, or see the TI web site at www.ti.com. (2) Eco-Status information: Additional details including specific material content can be accessed at www.ti.com/leadfree GREEN: Ti defines Green to mean Lead (Pb)-Free and in addition, uses less package materials that do not contain halogens, including bromine (Br), or antimony (Sb) above 0.1% of total product weight. N/A: Not yet available Lead (Pb)-Free; for estimated conversion dates, go to www.ti.com/leadfree. Pb-FREE: Ti defines Lead (Pb)-Free to mean RoHS compatible, including a lead concentration that does not exceed 0.1% of total product weight, and, if designed to be soldered, suitable for use in specified lead-free soldering processes. Over operating free-air temperature range; all voltages are with respect to GND (unless otherwise noted). PARAMETER VALUE UNIT 5V voltage range V5DRV, V5FILT –0.3 to 7 VIN, ENLDO –0.3 to 30 VBST1, VBST2 –0.3 to 37 V VBST1, VBST2 (w.r.t. LLx) –0.3 to 7 Input voltage range(2) EN1, EN2, VOUT1, VOUT2, VFB1, REFIN2, TRIP1, TRIP2, SKIPSEL, –0.3 to 7 TONSEL, VSW, LDOREFIN TRIP1, TRIP2 –0.3 to (V5FILT + 0.3) DRVH1, DRVH2 –2 to 37 DRVH1, DRVH2 (w.r.t. LLx) –0.3 to 7 Output voltage LL1, LL2 –2 to 30 V range(2) DRVL1, DRVL2, VREF2, PGOOD1, PGOOD2, LDO, VREF3 –0.3 to 7 PGND –0.3 to 0.3 Tstg Storage temperature range –55 to +150 °C TJ Junction temperature range +150 (1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) All voltage values are with respect to the network ground terminal unless otherwise noted. TA < +25°C DERATING FACTOR TA = +85°C PACKAGE POWER RATING ABOVE TA = +25°C POWER RATING 32Ld 5 × 5 QFN 2.320 W 23.2 mW/ °C 0.93 W (1) Dissipation ratings are calculated based on the usage of nine standard thermal vias and thermal pad soldered on the PCB. If thermal pad is not soldered to the PCB, the junction-to-ambient thermal resistance is 88.6 °C/W. 2 Submit Documentation Feedback Copyright © 2008, Texas Instruments Incorporated Product Folder Link(s): TPS51427 |
