• LTM4686 and -1 SVIN and INTVCC

    I want to replace an obsolete Intersil part with the LTM4686 (single output configuration) and I would like to design the replacement to use either LTM4686 or LTM4686-1 with 12V VIN.

    It seems from the datasheet I can just add a separate 5V LDO to supply…

  • LTM4686 overcurrent limit

    Hi,Support team,

    I evaluate DC2722 with the condition of attached settings.

    LTPowerPlay GUI ver.is latest (v1.5.1.0) 

    There are three unclear points about overcurrent limit function.

    a) The current limit works at greater than IOUT_OC_FAULT_LIMIT value…

  • LTM4686 in extended temperature ranges

    Hello, had a couple of questions on operating the LTM4686 beyond it's rated temperature oil and natural gas equipment:

    1. It is mentioned that the chip “ceases switching action if the control IC exceeds 160C” but will “resume operation after a 10C…

    After setting the output voltage with RVOUTnCFG and RVTRIMnCFG and starting up,

    we plan to change the voltage with VOUT_COMMAND.

    Is it necessary to change MFR_CONFIG_ALL [6] = 0⇒1b?

    Even if I do not change, sending VOUT_COMMAND will change the output…

  • LTM4686 question

    I have tested the LTM4686 demo,found there is a question.

    While the Run is low voltage(0V), and Vin voltage is about 12V,for the ideal condition, the output voltage should be 0, but I use multimeter to test the output voltage, found there is about 100mV…

  • Rewriting PSM when using LTM4686 in parallel drive

    I have the following concerns about using LTM4686, please let me know

    The LTM4686 is planned to be used in 4-parallel to drive 0.6V to the MCU.

    Pin-strapresistors configure start-upsettings(output voltage, register address, phase, etc)

    Since I want…

  • LTM4686 PMBUS寄存器转换公式


    LTM4686 通过pmbus读出的寄存器的值,怎么样转换为十进制数呢?是否有转换公式呢?如温度、电压、电流等。

  • LTM4686-1芯片的INTVCC用法

    LTM4686-1芯片的datasheet参考设计中,将INTVCC和SVIN接到一起,并将网络命名为 VIN_AUX,范围在 4.5V到5.75V,请问这个是外部提供给芯片的电源吗?

  • Question about using LTM4678 & LTM4675


    My customer use LTM4678 & LTM4675 in same design.

    So they ask about  the connection of SYNC pin and Share CLK pin between LTM4678 & LTM4675.

    Q1) Can they connect  SYNC pin in LTM4678 and SYNC pin in LTM4675?

    Q2) Can they connect  SHARE CLK…
