• RE: LTM4644 INTVCC pin

    Hi atrac,

    The INTVCC pin is disabled and goes low (though external discharge path) when the RUN pin is pulled low. The INTVCC can support up to 100mA depending on the required load regulation requirements for that voltage for the application. Note supplying…

    Hello, ask a question, can LTM4644 work in 1+1+2 mode?

  • RE: Problem importing gerbers from LTM4644 eval board design files

    Hi atrac,

    The Drill format is in Inches. For reference attached are 3 types of files that can be used for import instead of gerbers. Note DC1900A-3.tgz is the most popular format.

    Thanks

  • LTM4644

    In my application, there are two power supplies :12V/1A & 3.3V/3A . While I need three secondary power rails :①3.8V/1.1A  ②2.4V/1.84A  ③1.3V/4.85A .

    Can the following topology be achieved with LTM4644:

    VIN1:12V →VOUT1: 3.8V;(SVIN1=12V)

    VIN2:12V…

    你好,请问LTM4644的具体型号上,LTM464IY#PBF和LTM4644EY#PBF有什么区别吗?在手册上没找到相关说明。

  • LTM4644 enable problem

    1. In one of my project, I am using LTM4644 Step-Down Regulator for FPGA power. I give 5V power to Vin from power supply and I want to get 1V2 – 2V5 – 3V3 – 1V8 outputs; 5V is given to RUN1 – RUN2 – RUN3 – RUN4 pins from power supply. Third (3V3) and…

  • LTM4644 broken

    Hi sir,

    On my PCB board, I'm using two LTM4644 (totally 6 voltages levels output) to power on my main chipset

    first one has 3.3v(4A), 1.8v_1 (4A), , 1.5v(4A), 1.8v_2(4A)

    second one has  0.9(8A), 1.0(8A)

    and i'm using RUN and PGOOD to make the power…
