• ADP1047 at lower Vin,ac voltages

    Hello,

    Can I use ADP1047 at lower Vac voltages?

    Like 42Vac (35-55Vac) in at 50-60Hz. 
    Output 40Vdc, 1.7A.

    Or any other candidate from the product family.

    Thanks and regards

    HI,

    I plan to use ADP1047/8 with a 3 Phases AC input.

    If the passive rectifier output not reach the zero voltage, is that the product will work ?

    Regards

  • ADP1047, PFC output voltage regulation

    Hi

    I'm working on a PFC input stage built around an ADP1047. The input is 230 volt 50 Hz, the output 385 volt DC and the maximum power

    is supposed to reach 2100 Watt.

    It's working quite nicely up to a power level of about 800 Watt. If the load…

  • ADP1047 EVB connection issue

    HI,

    I am testing ADP1047 EVB and the ADP1047 output connect to a DC to DC.(Phase-shift).

    Now I find out that the Communication is very easy to lost when the DC to DC stage turn on.

    Is there any way to avoid the GUI to lost the communication with ADP1047…
