Hi,

I want to design a SMPS of Input 20V-260V DC, of 30Watts, with Multiple outputs of +12V, -12V, +5V, +24V.

I have experimented with Power Integration PWM controller DPA425R of Vin 20V-60VDC but the wattage is 12 Watts currently. Is there is any modification so that i can increase the input range from 20- 260V DC and also wattage up to 30Watts

Thanks
