• LTM4643

    Hello,

    when one of the four channels of the LTM4643 is disabled (by driving RUNx low), what is the status if VCCINTx and PGOODx ?

    E.g. pin RUN2 is tied to GND. Is VCINT2 regulator still turned on? Is PGOOD2 output driven low?

    Thank you,

    Josef Rypar

  • LTM4643 焊接问题

    Hello,

    我们单板在用LTM4643,在工厂生产的时候发现这个芯片BGA有焊接问题,切片报告显示:

    1. failure的点在下图红线的那一竖排的pin1/2/3.

    2. 断裂面比较平整

    请问这个问题一般是什么原因导致?你们客户是否有遇到过类似的问题? 谢谢

  • RE: Vdropout data of ADP1740/41

    Dear Alex,

    Thank you very much for your support.

    The input voltage is +1.5V from LTM4643. One LDO's output spec is +1.3V / 1A. Another one is +1.2V / 1A.

    Hope the copper area is minimized. So VOUT of LTM4643 is adjustable to be minimize VDO(Dropout…

  • Problems with LTM8049 power good pins

    Hello,

    I have a question to the power good pins of the LTM8049 vs LTM4643. I am using both in the same circuit. Both are enabled with RUN-pin from the same multiplexer. Both have a pull-up with 100k at their PG-pin and than drive a LED via an FDN357n…

  • RE: In your presentation you mentioned scalability of power, Can you elaborate what it is and does?

    It’s expensive and time-consuming for system designers to change their layout during prototyping to find the perfect DC/DC regulator to match unpredictable power consumption by ASIC, DSP, or FPGAs. So, here are 3 things we did to ease the pain for these…
