PTH12060W: Inhibit

ong sang jin
Prodigy 60 points
Part Number: PTH12060W

s1.Track pin coneected to Vin(12V)

2.Inhibit Pin used for getting Vout

-> We used moee than 100 boards using PTH12060W but one of them shows different waveform with others.

    When inhit(pin) is activated,Vout shows unstable for 20ms.

    I don't understand the reason...

    Just I guess that soldering of  PTH12060W track pin or inner connection is not correct then make 20ms period unstable..

    When this unstable can happens?

    Hi,

    Can you please show how you are driving the inhibit pin (e.g. snippet of schematic)? Can you also share oscilloscope capture showing Vin, Inhibit, and Vout pin waveforms when you toggle Inhibit? I would like to see what you mean by the unstable output for 20ms.

    Regards,
    Kris
