• RE: No output on ADP5074

    Hi apson,

    1. Please review 150uF cap at output and 100K soft-start resistor plus output current. Make sure current-limit is not violated during start-up and steady-state. You may use this as reference: www.analog.com/.../preventing-start-up-issues-due…

  • ADP5074 vs ADP5073

    I have a +5V to -15.5V inverter based on the ADP5073. Design based on the Design Tool. I used an output current of 100mA and the tool indicated ADP5073. Though the effective current on steady state is only around 20mA, the startup current is high due…

  • EVAL-ADP5074 documentation

    As previously with eval kit of the ADP5075, documentation is missing in the web page. Came on folks, that sends a negative message to prospective users of the part. At list to me it does.

    Anyway, can you provide documentation. I am considering testing…

  • ADP5074 will not turn on

    I have implemented a -6V and -15V power with the ADP5074.  neither will turn on.  I am including a snip of the schematic with these 2 devices.  Show me the fatal error.

  • ADP5074 EN can shut down the IC completely or not (no any VOUT)?

    EN can shut down the IC completely or not (no any output voltage in VOUT)?

  • RE: ADP5073 efficiency


    You need ADP5074 to get higher output current. Even then, ADP5074 at your input and output voltages can only provide up to around 0.8A. At 0.8A, efficiency will be about 72%.

    Hi SuzanneR,

    Please refer to Design Resources section of the ADP5074 product page. www.analog.com/.../LFCSP_16lds_3X3(CP-16-22).pdf

  • RE: a question about the parameters of the LTPower CAD

    You may want to check other inverting DC/DC products like ADP5073/ADP5074/ADP5075.  We have an available design tool in excel that can be downloaded from website. https://www.analog.com/en/products/adp5073.html#product-tools

  • RE: LTC7149 problems

    Hi ,

    The VOUT went slightly positive before going down. That's not expected.  Can you try isolating the load to see if this going positive is gone by using resistive load instead of an E-load? It may also help if you probe the VIN and SW…
