  • TPS7A25: power loss and efficiency date

    TI Thinks Resolved
    Part Number: TPS7A25 Hi, Could you please help to provide TPS7A2501DRVR power loss/efficiency data base on below condition? Simulation or calculation are both ok. Vin: 18V Vout(ADJ version): 18-VDO Vout(FIX version): 5V Iout: 300mA VDO:340mV

  • TPS7A25: Negative output

    TI Thinks Resolved
    Part Number: TPS7A25 Dear e2e support, Can we set the TPS7A25 to generate a regulated negative output, inverting the polarity on the output (GND and Vout)? The goal here, would be to generate a -2.5V from a Lithium Ion battery (3.0V-4.2V), to bias a sensor…

  • TPS7A25: Inrush current at startup

    Part Number: TPS7A25 The waveforms are checked when 12V is input to the power supply. In an application where the 12V power supply rises gradually, the input inrush current is 600mA. However, the inrush current is 3A for applications where a 12V power…

  • TPS7A25: thermal issue

    Resolved
    Part Number: TPS7A25 Hi Sir/Madam, i check the TPS7A25 datasheet. i have a source 12Vdc. output around 3.3 V / 1A. 1. T A(MAX) = T J(MAX) – (R θJA × P D ) T A(MAX) =125°C – [73.3°C/W × (12 V – 3.3 V) × 0.09 A] = 70.2°C…

  • TPS7A25: PSPICE Model not working

    Resolved
    Part Number: TPS7A25 Hello Team, the pSPICE simulation only works for Vout=1.24V. As soon as I add a voltage divider to the FB pin nothing works(= no output voltage). Thanks for your help! Hans

  • TPS7A25: Effects of output capacitance on inrush current

    Resolved
    Part Number: TPS7A25 Hi, I am planning on using TPS7A25 in an application which imposes a limit on total capacitance allowed during initial turn-on for the first 20ms to avoid tripping of the upstream inrush current limiter. How can I compute the total…
