• LTM8074 Startup time


    We observed some statup time of 300uSec from Vin applied until Vout ramp started.

    In our application we tied the RUN pin to Vin (=8v). SYNC is tied to GND. 

    There is no startup time parameter mentioned in the datasheet

  • RE: LTM8074 Inverting Application

    Hi orchardaudio,

    The connections look okay. You can use the inverting reference design on LTPowerCAD and then the LTM8074 model on LTSpice to verify your design. Please check page 17 of the datasheet for some rules of thumb for the PCB layout.

  • LTM8074 To find the average output voltage tolerance

    Hi team,

    We want to design a power supply with an accuracy of 5V ± 2%.

    We are considering excluding transient voltage fluctuations such as load regulation and line regulation.

    I think the LTM8074 is just right for us because the LTM8074 meets…

  • LTM8074 - SYNC input pin not working for me in LTSpice model


    I'm trying model a power system in LTSpice that is synchronized to a master clock.

    One of the components I'd like to use is the LTM8074.  

    I think I'm using it correctly , but I can't seem to get the operating frequency of the LTM8074 to sync…

  • Any leak to LTM8074 Vout pin


    I'm a DFAE in Japan. I have a question by our customer. If there is some leak current from the load to Vout pin of LTM8074 and -0.2V is generated between Vout and GND, will it suffer any damage to LTM8074? In this case, the Vin pin has no connection…

  • LTM8074 RT pin


    I'm DFAE in Japan. Our customer is evaluating LTM8074 and asked a question about RT pin to resistor.

    According to Page10 of LTM8074 DS, minimize capacitance at this pin. In order to get closer to the recommended resistor value listed in DS, when…

  • LTM8074 min off time

    I will use IN 12V out  9V(0.7A)

    Is there a minimum OFF time rule for duty?

    It looks like about 100ns in LTpowerCAD.

  • Driving the SYNC pin on the LTM8074

    If I drive the SYNC pin from a 74LVC inverter (3.3V CMOS output):

    1. should it be AC coupled?

    2. If AC-coupled should I pull-up/pull-down the SYNC pin at the LTM8074 side to define operation at startup?

  • 3D step model for LTM8074

    Is a 3D step model available for LTM8074?

  • Synchronize two LTM8074 with LTC6908-1 configured for spread spectrum

    Hi, I'm working on a design that uses two LTM8074 components, one for 3.3V and one for 5V. I want to synchronize them with a 180 degree phase shift using the LTC6908-1. I'd like to use spread spectrum if possible but, I'm unsure if the modulation rate…
