• RE: ADP1613 current drive

    Hi Ajith,

     

    The ADP1613 can NOT support 5V in 5.9V @2A out due to the current limit of the IC. The option is using ADP1614 instead of ADP1613. And the ADP1614 has smaller size ( 9mm^2 10-lead LFCSP) compared to the ADP1613 (14.7mm^2  8-lead MSOP). 

  • RE: ADP1613, inrush current at inductor

    Hi Usaghi,


    You are welcome!


    There is only one Figure in the ADP1614 Datasheet ( Fig 20) is related to startup, in which the operating condition for the ADP1614 is similar to that of the ADP1613 in Figure 32,33, starting up with precharged Cout…

    My understanding is that the Q1 switch in that figure is the internal FET in ADP1614... In the schematic capture above, there are essentially two FETs in series...

    Have a look at the ADP1621in the SEPIC configuration or the ADP1614 in the SEPIC configuration. Also, if your were not aware, we have this fantastic design tool called ADIsimPower. It is really simple to use, and they are excel based. See the links…

  • RE: ADP1614; Largest SS capacitor allowed?

    Hi Jonathan,

    The soft start capacitor Css can not be used for programming the startup time accurately for the ADP1614. The main function of Css of the ADP1614 is to prevent the input inrush current during startup.  Tss = Css*1.23V/5uA is the time that…

  • ADP1614 LOOP COMPENSATION

    Hi,

    There is a question about loop compensation of ADP1614.

    Hi Ricky,

    Please refer to the following schematic for driving LEDs in series using the ADP1614:
