  • ADP2118 Current Mode Output

    Hello

    Since ADP2118 has current mode output, I assume that it is possible to connect two or more of these converters in parallel to increase the current output. I want current output of 6A whereas ADP2118 can support 3A continuous current.

    But in the…

  • ADP2118: fixed Output FB Pin

    Could you please tell me with the fixed voltage versions of ADP2118ACPZ-R7
    should Rbot and Rtop should be connected?

     

    Please connet the FB Pin dirctly to Vout.
    The resistors Rbot and Rtop are implemented internally.

  • RE: LT1963 / LT3015

    Hi Jean,

    If you have computed Cff >=68nF, that would be your Minimum requirement Cff.
    Using 47uF would be far too much from the minimum required. 100nf would be advisable.
    *Note that the start-up time is affected by the use of a feedforward capacitor…

  • PGOOD terminal is floating. OK?

    Hi

    ADP2118's PGOOD terminal is open drain output.

    Is it ok floating when PGOOD doesn't use?

    Datasheet said PGOOD is an active high, open-drain output and requires a resistor to pull it up to a voltage.

    Any problem if that terminal was open…

  • RE: Load fluctuation data for ADP2120

    Kaos,

    load transient depends on the ammount of capacitance added to the output.

    You may want to consider using the ADP2120 design tool to identify how much capacitance you will need for a specific transient requirement.

  • RE: Switching regulator's output ripple.

    The transient response of a switching regulator depends on several factors; primarily the regulator’s architecture (voltage mode or current mode), the switching frequency, the value of output capacitance, and the inductor value.
