    Thank you for your help.

  • 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…

  • 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…

  • LTC7801

    If toggle RUN the LTC7801 will fail to turn back on. Output Voltage 13V output current 1A, input voltage 30V.  The BG did not short to ground the first time (as described in, LTC7801 issues Piyush04 on Jul 31, 2019).

    The device apparently recoved and would…

  • What are the LTC7801 / LTC3895 NDRV MOSFET power requirements?

    What kind of power is dissipated within the NDRV MOSFET?  I played around a bit in LTSpice and it appears to be <10mW.  I haven't seen much info pertaining to the selection of this feature.  I have a test PCB where I'm using a DMN24H3D5L for NDRV…

  • LTC7801 maximum current

    Hi, colleagues,

    how can I calcukate a maxumum current that is possible to get with LTC7801? What are thelimitations for MOSFETs?
