• LTC2924: DONE signal does not output Low

    Dear ADI engineer.

    We are designing a power supply system using the LTC2924.

    OUT1-4 are all High, and the four surrounding Power supply ICs are running. A voltage of about 0.9V is input to all IN1-4.

    However, the Done signal does not go low. The figure…

  • Simulation trouble in LTC2924 with DC/DC

    Hi

    Each LTM8024 and LTC2924 is a good result.(We use open macromodel's test fixture )

    But we put ICs in same schematic, LTC2924 out_n pin reach -100V order.

    If all LT8024 pins connect to GND, we get a bad result.  

    Can we improve this case with any…

  • Reg : LTC2924 - 200us delay - Simulation - Query

    We plan to use LTC2924 in our design, In the blog it is suggested as 200us can be achieved by using 1nF capacitor.

    But in my simulation, its taking around ~470us…

  • RE: LTC2924 , FAULT and On pin waveform

    Hi sir 

    Updated as below:

    Can you elaborate the test that customer is doing?

    Why does the ON pin goes low? This pin is connected to the EN pin of the NE555. Is NE555 pulling this pin low? 

    Ans : The output is 0.65Vout, the test state is in the Vin power…

  • LTC2924 6-Power Supply Sequencer question

    Hi sir

    My customer has 6-Power Supply Sequencer issues as below:

    1. by the specification P10 , circuit as below

        Confirm this output sequenced , in 6-Power Supply Sequencer , Is the output turned off at the same time?

         But can the Quad Power of outputs…

  • LTC2924 OUTx pin

    Hello

    Is it possible LTC2924's OUTx pin directly connect to Regulator IC's enable-pin which absolute maximum voltage below LTC2924's charge pump voltage?

    Because LTC2924 and LTC2928 is very similar power up/down sequence control.

    These…

  • LTC2924 datasheet TON / TOFF Calculation formula (P11 , Figure 6. Typical Power Supply Sequencer)

    Hi Sir 

    As below Figures 5 for spec P11

    My customer needs to know how this calculation RA/RB ?

    I still can't calculate the RA/RB value of Figure 5 according to this formula.
