• Buck circuit using LTC3810, its output current increase significantly.

    Hi !

    I'm beginer hardware engineer and for a power supply project we are very interested in your regulator controller. The LTC3810 is typically a component we are interested in to regulate 51V to 34V at 12V while providing 6A.

    We immediately bought…

  • LTC3810芯片没有输出

    供电电压48V,测试INTVCC处电压为10V,BOOST处电压为9.6V,FB和SW处电压为0V,VON处和VRNG处电压为10V,NDRV处电压为13V左右,ION处电压为1.33V,没有输出电压,请帮忙分析一下怎么解决!非常感谢!
  • LTC3810 Dead Time

    Referring Data sheet 3810fc for LTC3810 I can not find the specification of dead time between main output FET operations.  So how does one determine the largest gate charge that can be switched quickly enough?

  • LTC3810控制器技术

    在设计一款84-50V的DC-DC同步降压变换器(设计工作频率1MHz,最大输出功率100W)中,采用了贵公司的LTC3810作为控制器。在使用中,遇到了一些问题,所以想咨询下有没有相关的解决办法。
          目前遇到的主要问题就是,在开环测试及轻负载测试时,输出电压能够稳定输出约为50V,在输出电流约大于0.5A时,开启电子负载之后,输出电压降低,然后保持稳定(典型测试结果为当输出电流为0.5A,输出电压降至47V;当输出电流为0.6A,输出电压降至45V)。设计的电路原理图如附件所示。

  • LTC3810 - Constant Current Mode CC - possible?

    hi guys,

    how i have to design the ltc3810 circuit layout to get a constant current limited output? 

    1. we use a precast pcb product design

    2. we configurated the output voltage over the Vfb Voltage divider to 29,28V output CV

    3. we try to limit the output…
