PMP10948: 300V output with 4A max load

Nafis Ahmed

Part Number: PMP10948

Hello, I am a student with basic smps knowledge. I want to know if PMP10948 can be modified to set output voltage to 300V with 4A load capacity. It would be helpful if anyone can point out which component needs to be modified and the reason behind it.

Thanks

Hi Nafis,

There are two separate PFC stages in this design. They are not designed to be connected together.

Additionally the output voltage is set to 380V as it needs to be above the max line voltage. If you have a line voltage is that is lower than 300V you could set the output to that voltage. But if the Line voltage exceeds 300, then it needs to be set higher.

Hopefully this helps.

Lets say i use a step down transformer 220:110V and feed 110V to this module, after this which component determines the output voltage?
