• LTM4676 output voltage error

    Hi,

        I plan to design a 12V to 3.3V power supply module with LTM4676. The hardware design refers to a development kit of Altera, which can output 3.3V correctly.

    After powering up, the following digital IO pins of LTM4676 function correctly:VDD25, VDD33…

  • LTM4676/LTM4677

    当使用外接电阻确定LTM4676/LTM4677的输出电压时,是否还需要通过I2C总线对其进行控制?谢谢。

  • LTM4676/LTM4677

    Hi

         Can I set the output voltage of LTM4676/LTM4677 only using resistors which connect to relevant pins while without any control of I2C Bus?

       That means,if I do NOT write/read any message to LTM4676/LTM4677 via I2C bus,will the regulator output the…

  • LTM4676: I2C read is always 255 (0xFF)

    I am able to write LTM register via !2C but while reading the same register gives wrong value (0XFF) irrespective of any value.

    I doubt, is the read command needs any special format.

    Help Appreciated.

  • LTM4676A VIN_OV_FAULT_ LIMIT

    Hi folks,

    I've just tested a design with LTM4676A as a replacement for LTM4676. The configuration applied by pin-strapping (no programing needed).

    I did follow observation: In design with LTM4676 the limit of VIN is much higher than by LTM4676A…

  • Synchronizing multiple uModules

    I am using the following uModules in my design: two of LTM4678, LTM4677, LTM4676, and an LTM4686.  I plan to synchronize all at 500KHz and spread the phases to relieve the instantaneous current requirements on their common 12V input source.  I plan to use…
