hi,

I'm working on TPS65563a, Intially I got output perfectly,but now i'm not getting when i was sw output pin connecting to a pulse transformer, it shows different pulses compare to before when i'm getting output ,

I can't find where is the problem, please help me anyone, what is the problem

    Hi Sujith,

    Are you trying this with TINA model?
    If yes, then please share your tsc file with us?

    Thank you for your reply,

    I was not using TINA software, I am already purchased TPS65563A ICs 30 Nos, Working on this but am not getting outputs, 

    Now I got sw output but it came 7V Peak, before I got 25V peak on sw.

    I send you to my Circuit diagram and Output pulses images which I got, In that output images you find two different waveforms one is  Sw output which is with low peak voltage compare to other waveform and other one is transformer output.

    In the circuit I gave supply voltage 3.3V for VBAT, IPeak, VCC, XFULL  Pins and for chg pin I gave pulses from MicroController with 3.3V peak

    Please find the attachments, So, kindly suggest If any wrong connections are there in my circuit.
