• 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…

  • LTSPICE Simulation error

    Dear Team,

    Please help me find out what is going wrong in the LT spice Simulation.

    I have attached my Simulation file.

    My Input is 28VDC and I need a variable output (1.5V to 15V @10A).

    A 20K digital potentiometer will be used as feedback resistor(RFB2…

  • About the LTC3895 FET

    I am designing a circuit using the LTC3895.

    Why is not the provision of "BG, TG RMS Currents" in LTC3895?

  • RE: 请推荐DC-DC芯片，要求输入100V以内，输出24V15A以上，非隔离芯片

    24Vout@10A的方案都得需要外置的MOSFET，所以可以参考LTC3895/LTC7801/LTC3810/LTC3703。如果输入电压有可能低于24V的话，可以看一下LTC3779，LT8705A。
