  • TPS62770: Over consumption on DCDC step-down - 5mA

    Part Number: TPS62770 We have a product with a TPS62770 where the IC over consume. Over consumption of DCDC step doesn't go back to PFM when everything is disconnected from the output. Its stays in PWM mode, doesn't go back to low power and leads to battery…

  • TPS62770: /EN threshold

    Resolved
    Part Number: TPS62770 Hey, what's thte threshhold on the /EN pin for the TPS62770. We list a low of 0.4V and a high of 1.2V... can I drive it with 1.2V and get it to turn on? It clearly above to max low; but seems tight on the high level threshold. Is…

  • RE: Question about device TPS62770

    Resolved
    For the LED driver, the voltage would be limited by the built-in OVP circuit. What input voltage do you have? Do you need the buck converter inside the TPS62770? Just a reminder to title your posts without the word 'question'. Instead, put your…

  • RE: TPS62770 Voltage with current control

    Ahhh. We have a top of the line battery. I can't give the full specs, but the batteries are made by Tadiran (3.6V) and we've also thrown in an HLC Series battery.

  • RE: TPS62743: TPS62743 power select different from the EVM.

    Resolved
    Glad you can use the load switch. If you need a boost as well, please take a look at TPS62770. We also have TPS62808, if you need something smaller or with more output current.

  • RE: Battery performance optimizer circuit / rush current supplier with ultra slow quiescent current and high efficeincy

    Hi Zai, Check out this reference design which charges a super cap with 360 nA Iq: http://www.ti.com/tool/PMP9753 On the TPS62770, the LOAD switch just connects the buck output to the LOAD pin. You can see this in Figure 4.
