• LTC7004 with PWM as buck converter

    I've designed a PCB around the LTC7004 gate driver for stepping down 6-21V to a 3-4.2V LiIon cell.

    The INP pin is connected to a microcontroller which is deciding the duty cycle on a 6kHz PWM. Due to the input voltage possibly being over the absolute…

  • LtSpice Simulation LTC7004

    Currently I try to design a step down converter which will be controlled via a frequency generator. In order to drive the MOSFET (the one in the picture does not correspond to the real one) I use the High Side Driver LTC7004. In order to get a better…

  • LTC7004 recommended maximum VCC

    I am successfully using the LTC7004 high side NMOS driver in a design but have had issues with damaged parts. Due to the nature of the design there can be brief positive transients on the rail powering VCC on the order of +1 V over the nominal value of…

  • LTC7004 Failure

    I was using a LTC7004 to control the ON/OFF of a 8series LiIon battery. The nominal input voltage is 29.6V, the load is a constant power 160W camera. Use an electric load to do 160W constant power discharging test, sometime the LTC7004 is found broken


    When the discharging for the input battery is done…

  • LTC7004 - suitable for inverting buck-boost converter in DCM?

    Hello,

    I designed an inverting buck-boost converter which operates in DCM (discontinous current mode) and used the LTC7004 to switch an N-Channel MOSFET in a high-side configuration.

    In the simulation everything looks fine but when I designed the PCB…

  • LTC7004 for static application

    Hi all,

    I was led to this site for the following inquiry about the LTC7004.

    We're planning to use the LTC7004 gate driver to switch an N-MOSFET on and off to use it as a switch (basically it needs to stay on or off).
    The LTC7004 is powered by 12V…

  • LTC7001 - LTC7004 - turn off the inductive load

    Hi all,

    I use LTC7001 to turn on and turn off the power switch (several transistors connected in parallel). I disconnect 40 A current and then there is an overvoltage on the transistors.

    This is due to the inductive load.

    The documentation shows how to…

  • Problem in LTC7004 driver circuit

    I'm using LTC7004 driver. 

    When INP is low, TS signal is floating and oscillating as following image

    red signal: INP

    yellow signal: TS

    2V/div

    5ms/div

    How can I modify the above circuit to make TS signal 0 when INP signal is 0?

    Thank you,

    Francis…

  • LTC7004 dV/dt imunity?

    Hello everyone.

    I tried to use LTC7004 to drive MOSFETs on a specific application: Drain/source of the MOSFET is not tied to a specific voltage. dV/dt is close to 40V/10ns.

    I noticed that:

       - There is no dV/dt specified in the datasheet.

       - There is…
