  • RE: LMZM33606: Pin 14 NC

    Resolved
    Hi Alexander, Though pin 14 is no connect, I'd still suggest not routing through this pin. Figure 48 in the datasheet shows a top AGND copper plane with Rt connect to the plane through a via to the bottom layer. The team is currently working to clean…

  • LMZM33603: About efficiency curve data

    Resolved
    Part Number: LMZM33603 Other Parts Discussed in Thread: LMZM33606 , LMZM33606EVM Hi, Could you tell me about efficiency curve data Fig1 ? Is this data in forced PWM mode? If the data includes pulse skip, Do you have efficiency data for fixed frequency mode…

  • RE: LMZM33606: About reaction speed of external synchronization function

    Resolved
    Hi Yusuke-san, My hope is to spend some time today in the lab to bench test the synchronization on the LMZM33606EVM and provide you information today or by latest tomorrow similar to the data I got for LMZM33603. Sorry for the delayed response and I hope…

  • RE: LMZM33606: Fsw and capacitor values in normal and inverting applications?

    Hi, Unfortunately I didn't get a response from the designer on this expected efficiency drop. I plan on taking the LMZM33606EVM and configure it for positive output to measure the efficiency at 1MHz and 2MHz. That way I can at least provide you with…

  • RE: LMZM33606: LMZM33606 FB voltage issue

    Resolved
    Hi Liu, The reference of the LMZM33606 is set to regulate around 1V as you've seen in the datasheet. The 1.5V feedback voltage you see is for when you want to check the Iq current of the device. To get the part to a non-switching state, the feedback…
