Adjustable 150W PSU

Posted by: lukaszporadowski on

Hello,

can you suggest solution, using PI parts, for adjustable PSU (10V-300V range) capable to deliver 0.5A over the whole output voltage range (150W worst case)?

 

 This design is off-mains (85-265 V 50/60 Hz), so requires PFC stage as well. PSU shall have a possibility to adjust output voltage in 1V steps.

 

Is Hiper family a good choice to start with? Shall the design be calculated for 150W 300V and later output voltage can be regulated by decreasing the switching frequency of converter as in one of your design examples?

Hi,

 

We do not have  any existing reference design for your application.
