Hello.I have one of these chinese step up converters with XL6009(400KHz Switching Frequency).Can you suggest an output LC filter to decrease output ripple and noise further?
please be careful you dont make it unstable by adding too much output capacitance.
It already seems to have big output capacitor, so only light filter is needed, but then again, i dont know your app.
You could always sim it on ltspice, and then add some filter, as light as poss, and then see the ripple.
What is vout set to? What is vin set to? What is Pout?
Maybe i can try for you if you tell.
I was thinking something about L=1uH and C=10uF or 22uF (X7R or X5R type).I want to supply a small preamp or a small amp. Lets assume Vin=12V dc,Vout=48V dc and Iout=0.1A or 0.3A max.
Thanks guys.I am familiar with LTspice so no problem.I will search google for info about output filtering and ripple/noise reduction and i will come back...
