2 / 32 page TPS62231-Q1 TPS622314-Q1 SLVSB63 – DECEMBER 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. ORDERING INFORMATION(1) PACKAGE PACKAGE OUTPUT FREQUENCY TA PART NUMBER ORDERING VOLTAGE [MHz] DESIGNATOR MARKING TPS62231-Q1 1.8 V 3 DRY TPS62231TDRYRQ1 31 –40°C to 105°C TPS622314-Q1 1.5 V 3 DRY TPS622314TDRYRQ1 14 (1) For detailed ordering information see the PACKAGE OPTION ADDENDUM at the end of this data sheet. ABSOLUTE MAXIMUM RATINGS over operating free-air temperature range (unless otherwise noted) (1) VALUE UNIT MIN MAX Voltage at VIN and SW Pin(2) –0.3 7 V VI Voltage at EN, MODE Pin(2) –0.3 VIN +0.3, ≤7 V Voltage at FB Pin (2) –0.3 3.6 V Peak output current internally limited A Human Body Model (HBM) 2 kV ESD rating(3) Charged Device Model CDM) 1 Machine Model (MM) 200 V Power dissipation Internally limited TJ Maximum operating junction temperature –40 125 °C Tstg Storage temperature range –65 150 °C (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 network ground terminal. (3) The human body model is a 100-pF capacitor discharged through a 1.5-k Ω resistor into each pin. The machine model is a 200-pF capacitor discharged directly into each pin. DISSIPATION RATINGS (1) POWER RATING DERATING FACTOR PACKAGE RθJA FOR TA ≤ 25°C ABOVE TA = 25°C 1 × 1.5 SON 234 °C/W(2) 420 mW 4.2 mW/ °C (1) Maximum power dissipation is a function of TJ(max), θJA and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = [TJ(max) – TA] /θJA. (2) This thermal data is measured with high-K board (4 layers board according to JESD51-7 JEDEC standard). 2 Copyright © 2011, Texas Instruments Incorporated |
