  • TPS62122: Input impedance

    TI Thinks Resolved
    Part Number: TPS62122 Hi Team, A customer wants to know the input impedance of TPS62122. Do we have this information? Regards, Danilo

  • RE: TPS62122: Input impedance TPS6212

    Tom, It seems to me that we are getting hung up on the terminology here, and it is not the input impedance of the TPS62122 device that you need for your model. Instead, it sounds like you are trying to model the "effective load" that your Energy Harvesting…

  • TPS62122: Power up using quantity 2 of the TPS62122 and having only 1 ma of current available

    TI Thinks Resolved
    Part Number: TPS62122 I have a 6.6 volt input for Vin and only 1 ma of current available limited by a constant current diode. My supply has 2 outputs 2.7 and 1.8 using 2 of the TPS6212s. I power up fine but if I raise the input power slowly or jiggle…

  • RE: TPS62122: TIDA-00690 - Efficiency with TPS62122

    My schematic is the same as TIDA-00690 eval board. If I supply separetely TPS62122, the efficiency is about 80-85% but the context is different : with a power supply the DCDC is in "constant mode". With the harvester, we consider the transient of start…

  • TPS62122: Buck converter survey

    TI Thinks Resolved
    Part Number: TPS62122 I'm surveying Buck converter. The condition is as below: Buck converter: input voltage >= 7V, output voltage: 2V ,Iout>0.05A, ultra low Iq, smaller package. Is TPS62122 the best solution? Thanks.

  • TPS62122: Question about output current

    Resolved
    Part Number: TPS62122 In the data sheet of TPS62122, there says Output Current is 75 mA. I have two questions for this output current. 1. Is this mean TPS62122's maximum capable current is 75mA? What happens is loader takes more current than 75mA?…

  • TPS62122: Negative voltage on VIN: allowed..?

    TI Thinks Resolved
    Part Number: TPS62122 Hi, looking for every option to save power in battery designs I would like to save the diode that typically sits between the battery (coin cells or whatever small stuff) and the power circuit. This diode takes ~ 0.5V of my small power…

  • TPS62122: Similar part that shutdowns Vout completely
