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 my affect device reliability. (2) All voltages are with respect to network ground terminal. (3) Limit the junction temperature to 105°C for continuous operation at maximum output power. (4) Limit the junction temperature to 105°C for 15% duty cycle operation. (5) In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may have to be derated. Maximum ambient temperature (TA(max)) is dependent on the maximum operating junction temperature (TJ(max)), the maximum power dissipation of the device in the application (PD(max)), and the junction-to-ambient thermal resistance of the part/package in the application ( θJA), as given by the following equation: TA(max) = TJ(max) – (θJA X PD(max)). To achieve optimum performance, it is recommended to operate the device with a maximum junction temperature of 105°C. 9.2 Handling Ratings MIN MAX UNIT Tstg Storage temperature range –65 150 °C Human body model (HBM), per –2000 2000 V ANSI/ESDA/JEDEC JS-001, all pins (1) VESD Electrostatic discharge Charged device model (CDM), per JEDEC –1000 1000 V specification JESD22-C101, all pins(2) Machine Model - (MM) –200 200 V (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. 9.3 Recommended Operating Conditions MIN NOM MAX UNIT Input voltage range 2.30 4.85 V VI Input voltage range for in-situ customization by E2PROM write operation 3.4 3.5 3.6 V L Inductance 200 470 800 nH CO Output capacitance 9 13 100 µF IL Maximum load current during start-up 250 mA TA Ambient temperature –40 85 °C TJ Operating junction temperature –40 125 °C 6 Submit Documentation Feedback Copyright © 2014, Texas Instruments Incorporated Product Folder Links: TPS61280A TPS61281A TPS61282A |
