• RE: LTC3891 - maximum voltage adjustment range ?

    The output voltage is set by the feedback resistors, can be found in page 18 of the datasheet. In page 14 of the datasheet that talks about the SENSE pins, it mentions taht LTC3891 is able to regulate output voltages up to a nominal 24V.

  • RE: LTC3372

    We will not have an LTC3372 LTPC model for a few months. Meanwhile, the LTC3891 LTPowerCAD model or LTspice model can be used to model the LTC3372 HV converter. 

  • LTC3891 RUN pin noise

    I am currently utilizing the LTC3891 with a 499k between PWR and RUN and a 100k between RUN and GND.  I do not need the UVLO function, and I believe I am potentially picking up noise on this device that is causing the RUN pin to go low.

  • DCR Sensing

    Hi,

    I would like to know is there any difference on the placement of the Inductor DCR sensing.

    On the datasheet of LTC3784 the DCR sensing the capacitor and resistor is parallel, whereas on the application note 136 using LTC3855 the application note…

  • LTC3897 Boost Controller Voltage Input Range

    I want to use the LTC3897 Boost Controller with input range from 9V to 32V and an output of 48V.
    I have the DC2108A Demo Board which supports inputs from 16V to 55V and output of 48V.

    There is a reference design in the LTC3891 datasheet that claims to…

  • 请教一下关于LTC3891开关电源遇到的开关频率调节问题

    LTC3891测试.rar最近在使用LTC3891做DC-DC时,遇到这个问题:在进行开关频率调节的时候,根据数据手册所给的要求,对FREQ引脚的下拉电阻进行不同值的调试,同时也进行了分别接到GND和INTVCC两种状态去调试,发现TG和BG上的频率与数据手册所给的频率图表对不上,每一值都相差10倍左右,测试时是将MOS断开进行测试的,请问这是什么情况?附件中为我的测试记录和原理图。
