• LTC1624 : noisy Ith/RUN pin with shutdown N-MOSFET

    Hi,

    As suggested in the datasheet, I added a type N MOSFET between the Ith/RUN pin and ground, in order to shut it down, like in Fig 3b, page 10. On the same board, I made 3 LTC1624-based power supplies (+12V, +5V and +3.3V). All 3 share the same +24V…

    Hi, 

    Will the LTC1624 be able to output 28V, 1.2A from a 12V input? 

    Thank you.

  • LTC1624输出异常

    Hi ,各位大哥哥小姐姐,

         我用LTC1624设计了一个24V转5V的降压电路,功率大概5V@1A。

         偶尔会发生,在上电的一瞬间,电源芯片会发生异常,导致输出电压只有2点几V。且需要断电重启,才能恢复。

    请问是什么原因导致该现象,该如何解决?

    下面是原理图以及异常情况下各管脚波形。

         原理图如下:

    TG:

    ITH/RUN:

    VFB:

    BOOST:  5V

  • LTC1624 TG、SW波形异常

    各位专家大家好:

         项目中使用LTC1624这个IC,用于24V to 5V@1A,原理图如下

    现在测试发现 TG 以及 SW引脚的波形异常,黄色为TG、紫色为SW。但是输出5V是正常的。

    请帮忙分析一下为何会产生该现象,谢谢~
