• LTM4677

    1. what's the precision of TOFF_DELAY. 2 digits after decimal or 3? 

    for example, both 2.43ms and 2.435ms are OK?

    2. can it be set to 0.025ms or 0.03ms? 

    Thank you.

  • Question about using LTM4677 EVM (DC2481B-A)


    My customer is testing the performance of LTM4677 thru DC2481B-A (ADI EVM).

    Their test condition is like below and they added R7 (0ohm) between Vin and Inrvcc as the guide in schematic because of  applying 5V at Vin .

     Test Condition : Vin 5V  /…

  • Questions about initial register setting of LTM4676A & LTM4677


    My customer decides to use LTM4676A and LTM4677 in their system.

    At their system, the operating condition of LTM4676A and LTM4677.

                  A. Vin : 5V

                  B. Vout : 1V

    But when they test with ADI EVM, the initial value of VIN_ON isn't support 5V Vin because…

  • LTM4677  PolyPhase operation

    I will use LTM4677 single output(OUT0=OUT1)

    LTM4677 Device output is connected to DSP.

    So I can't change the value ”MFR_PWM_CONFIG”  [7] 0 to 1

    (The part must be in the OFF state to process this command. )

    What happens if the value here…

  • LTM4676/LTM4677


         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…

  • RE: LTM4676/LTM4677

    Frank, 你好!请问 LTM4677 能不能支持 DC1613A 以外的 I2C Dongle?比如说用 FT2232H 的 I2C 在线控制 LTM4677 的 register 去进行调压或者开关。

  • We use a couple of LTM4667/LTM4677 for our board which we want to cool with liquid.

    We use a couple of LTM4667/LTM4677 for our board which we want to cool with liquid. Is it better to cool it though the PCB instead of the top? In the data sheet the thermal resistance looks still smaller on the bottom. Our proto board shows cooling through…

  • how to set OCP when use LTpowerplay?

    I buy demo board(DC2481A-B) on digikey,  LTM4677(X1) & LTM4650(X3)

    1. it only detect one LTM4677 when LTpowerplay trun on.

    Is this correct? please refer the attachment. 

    2. IOUT_OC_FAULT_ LIMIT maximum is 30A, 

    Does it can output 1V 186A?

  • RE: DC1613A with umodules, what pins do I need

    Hi Nathan,

    Is it possible to use FT2232H USB to I2C dongle to access and control registers of LTM4677 instead of using DC1613A? Thanks!
