• LTC7801 Current Sensing Complexity

    Hello,

    I am trying to design a very efficient variable output voltage buck-converter using the LTC7801 that generally performs >97% across as much of the load range as possible and >99% for the Vin=Vout=24V 100% duty cycle case. To this end, I have found…

  • LTC7801异常损毁

    LTC7801EFE#PBF

    VIN:0-60V

    VO:16.8-28V/5A

    一旦上电,无论供电多少-无负载,与TG脚串联MOS都会损毁,GS击穿,但与BG相连的下臂MOS正常运行

    怀疑是不是外部电路配置异常

    需求帮助,

  • LTC7801, connect 5A load = failure

    The LTC7801 with 40V input voltage and 5V output voltage without load and 5A connected load is stable.
    With a voltage of 80V without load, it works and when I add a 5A load, the LTC7801 system is damaged.
    After fitting the new LTC7801 there is the same…

  • [LTC7801] Output capacitor issue

    Hello,

    I designed several power supply converting 49V into 12V (7A) but output tantale capacitors are destroyed after power-up, do you know what happened?

    Please find the design in attachment. PDF

    The tantale capacitors are TR3D157K016C0075.

    Beside, after…

  • LTC7801 SGND/PGND SEPERATİON

    Hello Everyone

    I am using LTC7801 controller for a sencron buck converter application. The converter has wide input voltage range. I was produced a prototype. When I tested converter I recognised that I have stray inductance on layers. Because of that…

    Thank you for your help.

  • LTC7801 Buck Controller

    Hello everyone

    I'm using LTC7801 controller for a buck converter application. When I tested light load modes is that Burst,Pulse-Skipping and FCC, I recognized that switching frequency was changed in both burst mode and pulse skipping mode. Switching…

  • Questions about output voltage drop of LTC7801

    Hello,

    My customer use LTC7801 like attached schematic.

    And when they test this circuit, they found about 0.9V voltage drop at output terminal.

    They use below test condition and LTC7801 circuit in attached schematic.

         1. Vin : 57V, Vout: 5.6 or 5.7V…

  • LTC7801 fails sporadically

    Hell everyone,

    we are having some problems using the LTC7801 buck converter IC. We use the device with 48V input voltage and provide an external voltage of 11V for the gate drivers. Apart from that, the circuitry is strongly based on the reference design…
