TOP258PN - 10W power supply design
Posted by: monil9
on
Dear sir,
I am designing a new power supply with TOP258PN
IP voltage range - 100VDC to 450Vdc
Op : 350Vdc @30mA
Transformer Details :
Primary - L 1050mH - 30Turns - 26SWG
Secondary - L 10mH - 100Turns - 25SWG
Aux 1Turns
Please find an attched schematic diagram.
Problem: Power supply not working continuously. it works on and off continuously.

yes, sir, the waveform is like a sawtooth.
approx 2-3hz.
I request you to give me all the designs for 350Vdc 30mA including transformer.
designing it for INDUSTRIAL PRINTER POWER SUPPLY
Hi!
Could you attach the sawtooth waveforms that you mentioned? Did you design the schematic using PI Expert/PI XLS? If so, may I see the spreadsheet/reference design from PI Expert?
Thank you.
Regards,
Good day!
Do you have drain voltage, current waveforms of the power supply during this state? Can you say how long(in seconds) the power supply turns on/off continuously? Thanks.
Regards,
