AC or DC input to DC output SMPS circuit design
Dear all,
I want to design an SMPS circuit with the following specifications:
* Input can be either 33-265 VAC or 48-375 VDC
* Multiple DC outputs (eg. 5VDC, 10VDC etc. )
* Output power (40-100W)
I am not able to enter these parameters into PI expert to make my SMPS design.
I have attached the design I made for 88-265VAC input. How to modify this circuit with the specifications above?

Hi dear,
Iam working in digital overcurrent protection relay which has many functions and needs diffrent dc supplies like 24dc , 10dc , 5dc , and 3.3 dc.
This kind of devices has standard of supplying methods which they are supplying with input of
33-265 VAC or 48-375 VDC
Iam looking forward for your reply.
Zaim.
Hi zaim,
Thank you for your prompt response. For your required inputs, currently we don't have a specific product with the given input capabilities. For lower input range you may consider our DPA-Switch, provided on the link below :

Hi zaim,
Thank you for your interest in using Power Integrations product in your design.
May I ask what application of your SMPS design that requires a very low input so we can further review your design requirements?
