4 / 30 page TPS630250 TPS630251, TPS630252 SLVSBJ9B – MAY 2014 – REVISED MARCH 2015 www.ti.com 8 Specifications 8.1 Absolute Maximum Ratings (1) over junction temperature range (unless otherwise noted) VALUE MIN MAX UNIT Voltage(2) VIN, L1, EN, VINA, PFM/PWM –0.3 7 V VOUT, FB –0.3 4 V L2(3) –0.3 4 V L2(4) -0.3 5.5 V Input current Continuos average current into L1(5) 2.7 A TJ Operating junction temperature –40 125 °C Tstg Storage temperature range –65 150 (1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) All voltage values are with respect to network ground pin. (3) DC voltage rating. (4) AC voltage rating. (5) Maximum continuos average input current 3.5A, under those condition do not exceed 105°C for more than 25% operating time. 8.2 ESD Ratings VALUE UNIT Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±2000 V(ESD) Electrostatic discharge V Charged-device model (CDM), per JEDEC specification JESD22- ±700 C101(2) (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. (2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. 8.3 Recommended Operating Conditions (1) MIN TYP MAX UNIT VIN Input Voltage Range 2.3 5.5 V VOUT Output Voltage 2.5 3.6 V L Inductance (2) 0.5 1 1.3 µH Cout Output Capacitance(3) 20 µF TA Operating ambient temperature –40 85 °C TJ Operating virtual junction temperature –40 125 °C (1) Refer to the Application Information section for further information (2) Effective inductance value at operating condition. The nominal value given matches a typical inductor to be chosen to meet the inductance required. (3) Due to the dc bias effect of ceramic capacitors, the effective capacitance is lower then the nominal value when a voltage is applied. This is why the capacitance is specified to allow the selection of the nominal capacitor required with the dc bias effect for this type of capacitor. The nominal value given matches a typical capacitor to be chosen to meet the minimum capacitance required. 4 Submit Documentation Feedback Copyright © 2014–2015, Texas Instruments Incorporated Product Folder Links: TPS630251 TPS630252 |
