• ADP1071-1 evaluation board not working

    Hi i am testing the evaluation board of ADP1071-1 for the first time.

    I am not getting proper output voltages at any laod condition.

    The Vreg1 is showing around 9V and gate pulses are coming when i turned on 24V.

    The pulse width of gate pulse is only…

  • regarding the ADP1071-1/2

    In the datasheet of ADP1071-1/2, the peak gate drive current on GATE and SR pins are not mentioned in the datasheet. Any inputs on this?

  • ADP1071-1 : Start Up Behavior

    I'm designing in ADP1071-1 PWM controller to regulate a two-switch flyback auxiliary power converter. As I'm going through the design I've encountered a few gray areas I was hoping to gain some insight on.

    1. The "GATE PIN" of the ADP1071-1…
  • RE: ADP1071 startup intermittent

    The User Guides for the three evaluation boards all have Figures that show an example PCB Layout:  ADP1071-1EVALZ, ADP1071-2EBZ3.3V and ADP1071-2EBZ12.1V.  The ADP1071 Data Sheet has a section called LAYOUT GUIDELINES. 

  • ADP1071-2 evm 36W 12.1 VOUT

    Hello , I have some questions regarding adp1071-2 evalutaion board for 36 Watt (12V1 Output).

    1) Is there a Ltspice model for the adp-1071-2 controller ? and if not , can you create one?

    2) is there a minimum load condition for the adp-1071-2?

    3)what is…

  • RE: Can you clarify how to set the switching frequency of ADP1071?

    Apologies for the confusion. Please treat R_TOP+R_BOT= R and place R on the RT pin to AGND1. See fig 27 for more details below.


    I will make a change to the datasheet…

  • RE: Are there models of ADP1074 and ADP1071-2 for LTSPICE available?

    The ADP1071-2 will indeed be a good fit for this. The ADP1071-2 is in pre-release status so the full datasheet is not yet available. However, it is exactly similar to ADP1074 (active clamp forward converter) with fewer pins. I suggest you contact the…

  • AD9523-1  Can I precisely adjust output clock frequency with AD9523-1 (EVAL-AD9523-1)?


    I would like to inquire if it is possible to achieve precise frequency control with EVALZ - AD9531-1? I'm interested in generating a clock signal that is a multiple of femtosecond laser output pulse rate, which can be something close to 80…
