  • TPS61070: Efficiency at VIN=1.8V, VOUT=3.3V, Iout=30mA

    TI Thinks Resolved
    Part Number: TPS61070 Other Parts Discussed in Thread: TPS61071 , Hi, How much is efficiency at Vin=1.8V, Vout=3.3V, Iout=30mA? I cannot read from the datasheet. Best Regards, Kuramochi

  • TPS61070: Quiescent current of TPS61070

    TI Thinks Resolved
    Part Number: TPS61070 Hi My customer evaluated the quiescent current of TPS61070. When they raised VBAT from 1.2V, IQ had kept on raising until VBAT=3V and dropped by degrees after that. The condition and result are the following. Are these results…

  • TPS61070: L calculation

    TI Thinks Resolved
    Part Number: TPS61070 In the datasheet, there are some steps in the inductor calculation that appear to be missing or unclear. For equation 4 on page 13, I put in these values for the example: Vbat = 0.9V, Vout - 3.3V, ∂I(L) = 40%, f = 1.2MHz, I(o) …

  • TPS61070: A01

    TI Thinks Resolved
    Part Number: TPS61070 Tried the configuration given in datasheet for 3.3V output through a supercapacitor rated at 2.5v. It is not working properly, only boosting upto 2.59V. What else should be taken care of?

  • TPS61070: Input voltae question.

    Resolved
    Part Number: TPS61070 Dear TI Team. I am trying to set the input voltage 2.1 ~ 3.3V output voltage to 3V with TPS61070. The TPS61070 does not have a power path, so I want to check if the output voltage is bypassed when 3.3V is input. I would like to inquire…

  • TPS61070: Power Save mode threshold voltages

    TI Thinks Resolved
    Part Number: TPS61070 The datasheet says that for power save mode the TPS61070/3 will enter Power Save mode when the inductor current reaches zero. Then the device will stop switching until the output voltage reaches a certain threshold and then turn…
