• ADP2504  Issues with supplied current and current limiting

    The ADP2504 not achieving the max 1 amp as defined in the spec.

     

    The ADP2504 is designed to start-up with a maximum of 100uF, if you have
    additional capacitance besides the 22uF shown on the datasheet schematics that
    may result in the output voltage…

  • Leaky ADP2504

    We are using an adp2504acpz-r7 and it is generally running very well.  It's bucking and boosting properly and is able to properly power a cellular module without much trouble.

    The problem we find is that it seems to be leaking current when we shutdown…

  • ADP2504-5.0 Heat/Swithing on&off Issue

    Hi,

    I am having an issues using ADP2504-5.0 .. If I powered it up without any load connected it outputs 5v.. Once I put a load (< than 50ma [a Micro Controller]) It starts switching on and off.... And starts getting very hot....

    Any ideas?

    Here's…

  • ADP2504 Issues at programmed voltage

    HI.

    Having some stability issues with the ADP2504.

    We have programmed the voltage output to be 3.52V using R1=340k and R2=56.2k (1% resistors).

    Upon startup the voltage is wild with high-frequency ripple then it settles out. at around 3.5V.

    When smoothly…

  • ADP2504-5.0: output voltage incorrect at 1.8V

    Hi!

    I need some help with my use of the ADP2504-5.0. I used the ADP2503_04_BuckBoostDesigner spreadsheet to design my circuit with the following parameters: Minimum input voltage = 3V, maximum output voltage  = 4V, Output voltage = 5V, Output Current…
