• LTC3226 transition

    The datasheet for the LTC3226 states in the "Programming the Input Voltage Threshold for the Power-Fail Comparator" section on page 11:

    For a smooth transition from normal to back-up mode, the PFI threshold should be set 50mV to 100mV above…

  • LTC3226 Output

    Hi, 

    I am designing a circuit with the LTC3226, and I took a look at people posting circuit design from this support community. Some people have added a Zener 3V3 at the output to make sure output stay below or equal at 3V3 I assumed?. Is it really necessary…

  • LTC3226 LDO range

    Hello,

    I use ltc3226 with one supercup 70F for backup power in a mini logger.

    I set the LDO to 3V and I want to give me power till 1.7V Is it possible ?

    Now power off at ~ 2.7V (3V-7.5%) 

    Tnx

  • ltc3226 LVO range

    Hello,

    I use ltc3226 with one supercup 70F for backup power in a mini logger.
    I set the LDO to 2.9V and I want to give me power till 1.7V Is it possible ?

    Now power off at ~ 2.7V (2.9V-7.5%)

    Tnx,

    Giannis

      

  • 超级电容充放电 芯片LTC3226

    主电源最大功率只有700mW,而电路正常运转时此功率能够满足,但某些时刻峰值功率达到1.5W,能量供给不足,导致电路故障,故采用超级电容作为补充,试了下LTC3226芯片,发现其只能是主电源和超级电容备份电源其中一个工作,两个不能同时为电路供能。请问是我的设置错误,还是此款芯片只能选择一个电源。如果是设置错误,该如何设置;如果是芯片原因,应该选择哪款芯片能够使得主电源和备份电源同时为电路供能?

  • LTC3226 consumption

    Hi,

    I'm using LTC3226 to charge 2 supercapacitors (2.7V 350F) mounted in series. The charging process is OK with CPO (full charge) = 5.3 V and Rprog = 105K that leads to 120 mA of charging current.

    When the main power is disconnected and the Vout…

  • Need help on LTC3226, it is not charging...

    The above is my test circuit, 5V is confirmed on VIN, but I don't see any voltage on CPO, nor C+, C1, what did I do wrong in the design?

    Thanks for any pointer!

  • Fast and safe supercapacitor discharge

    Hi,

    My backup power uses 2 series supercapacitors (2 x 350F 2.7v = 5.4v)

    I need to modify the design in order to add a fast discharging circuit.

    The discharge should be fast and safe. (less than 2-3 min).

    The switching during normal use (charge and powering…
