• LTM4657 and external PMIC (ADM1266)


    are there any special considerations for using LTM4657 when system margining is done by ADM1266?

    Idea is to place Vosn+ and Vosns- of LTM4657 at the output ceramic and ADM1266 sense at the pins of FPGA and perform margining using that.


  • RE: ADM1266 PDIO Issue

    Hi rmalavi,

    Apologies for the delay. We hope you fixed the issue already. If not, can you send your ADM1266 configuration file? We can take a look and determine if there might be a possible timing issue causing the failure. Thanks.

  • Automated programming of ADM1266


    A customer of ours needs us to program a pair of ADM1266 devices on their board in an automated environment.

    I am familiar with using I2C and SMBus in an automated test system using standard I2C/SMBus hardware in a LabView environment.

  • ADM1266 Leakage Current


    I've taken over support for a CPU board developed by another engineer at Arista.  In this design, there's a 3.3V CR2032 coin cell which is converted to 1.5V by an ADP162 LDO.  This rail feeds the RTC of the x86 and is monitored by VP11 of…

  • PMBus interface for ADM1266


    What programmes/adapters does ADI Power Studio support becides ADP-I2C-USB-Z?

    Is it possible to use custom "on-board" usb-i2c(pmbus) interface for ADM1266? What can You recommend for this?

  • ADM1266 State transitions

    When the ADM1266 Sequencing Engine triggers a State change, if the old and new States have the same GPIO or PDIO Output state (high or low), does the output glitch at the transition?

    (I can evaluate on an Evaluation Board, but am awaiting delivery).

  • ADM1266 Configuration programming issue

    Hi ADI Expert

    I used my test tool to program the  ADM1266 configuration as the procedure noted in AN-1453

    Here are my steps:

    Step1.Set STOP SEQUENCE 0x11 ,delay 100ms, READ_STATE (0XD9) and get 0x00

    Step2. set UNLOCK ADM1266, delay 10ms, READ STATUS_ MFR_SPECIFIC…

  • ADM1266 Evaluation Board issue

    Hi Sir

    I have got 1 set EVAL-ADM1266 from Digikey, but we can't find the ADM1266 POL evaluation board. 

    So I would like to ask if there is any way to use ADI Power Studio for demonstration without POL?
