    lt8580芯片的数据手册里,有部分公式缺少运算符号,所以我不太很确定电路中的器件该用什么值。

  • Timing to operate the SYNC pin of LT8580

    I have a question about LT8580.

    I'm considering of how to put the frequency of the external clock 500KHz into the SYNC pin.

    RT pin is also set to 500KHz.

    The timing to put the external clock is not specified in the data sheet.
    Is there any particular…

  • Synchronizing LT8580s

    I have a requirement for an audio circuit that runs from a +30V supply rail but needs a -10V bias supply for a couple of JFETs in the circuit. It is intended to run from a 9V battery. I can use 2 LT8580s to generate the voltages needed but my concern…

  • LT8580 Frequency Foldback

    I need a boost converter (200mA @ 19V) that needs to be synchronized to an external 1.25MHz clock.   This part does support synchronization, but does the Sync feature disable the Frequency Foldback?   Or does Foldback still occur under light loads.   I need 1…

  • RE: dc-dc-inverter with LT8580

    Hi dulcevita,

    thanks again for your help.
    As the LT8570 is pin compatible to LT8580, I can replace it on my pcb.
    So for now, my question ist answered.

  • RE: LT1930 Dual Output Converter Topology

    Hi Jeronym,

    Sorry for late reply.

    The circuit shown is essentially a charge pump. The capacitance values are sized for the 1930 switch current limit and therefore are optimized. The positive rail is regulated with the FB divider network and the negative…

  • RE: LT3905 Sipm Design Review

    Your approach seems sensible. Just know the Fsel tied to ground will lock you into a 1MHz switching frequency.

    Now, since you intend to use this part as a simple boost, know you will only have a few mA of load current at your disposal. If you need more…

  • LT8570 datasheet equations

    Hello, I am designing an inverting boost converter with the LT8570 and created a spreadsheet using the equations on page 24 to calculate max output current.  I set up the inputs to match the circuit diagram shown on that page, but my calculations for output…
