• ADP1614 SEPIC/CUk Unable to switch with components designed from ADISimPower

    I have designed SEPIC/CUK from ADISIMpower Excel Sheet with 2.7-4.5 Vin to +/-5.5 at 0.4A. Due to low ripple requirements and low Vstep, Output caps are large like 3x 100u for each.

    Similarly, just for study purpose I simulated LT3579 SEPIC Converter…

  • ADP1614 Severe Overshoot on Step Load

    Hello experts,

    We have a boost 3V to 5V built around ADP1614ACPZ-650-R7

    The image attached shows 4 output voltage changes when removing a load (using a KEL103 electronic load in CC mode).

    Apparently, the output voltage overshoot upon a falling step load…

  • ADP1614 SW pin Maximum Negative Voltage

    What is the maximum negative voltage the SW pin can sustain?

    Datasheet only states "21V" while all other pins have a voltage range, not a single value.  SW pin can usually sustain some negative voltage.

    I have some undershoot at turn on.  Worst…

  • RE: ADP1614 Rcl value

    Hi

    I have Web meeting with our customer today.

    But Our cutomer does not know the reason of the peak current limit.

    End customer does not tell the reason to our customer clearly.

    I close this question

    Best regards

  • ADP1614 CUK/SEPIC

    Can someone explain the "extra" MOSFET in the CUK/SEPIC configuration of this circuit?  It is shown in the output of the Excel design tool, but it is not shown in app note AN-1106.

  • Large Ripple at the ADP1614 Output

    The above image shows the schematics of the two-stage boost conversion. 

    Stage 1: Battery/Bench-top power supply to ADP1614 to obtain regulated 5V output. The 5V is then used for the following:

               a. It connects to an ADP7104 (P3 on the schematic) which…
