Need help for AC-DC power supply design: 230Vac input, 60Vdc and 20W output

Posted by: mchung725 on 02/24/2013

LNK306 is not enough power for making AC-DC power supply design: 230Vac input, 60Vdc and 20W output.

Any recommendation?

Hi,

I am assuming you are designing a non-isolated buck topology. LNK306 is capable of delivering 20W at 60VDC output for the input voltage of 230VAC when the convereter operates in CCM mode. Try to increase the inductance value so that it reduces the peak current and increases the total power delivery.
