Question
AC or DC input (ultra-wide input)to DC output SMPS circuit design ?
Dear ST team,
I want to design an SMPS circuit with the following specifications:
* Input can be either 33-265 VAC or 48-375 VDC (ultra-wide input)
* Multiple DC outputs
1.output : 24V with 0.7 A
2.output : +10V with 0.8 A
1.output : -10V with 0.8 A
1.output : 5V with 0.5 A
1.output : 3.3V with 1 A
* Output power (40-100W)
.
How to design an isolated power supply circuit with the specifications above ?
How can I make the transformer calculations according to this circuit? Is there any softwares to do that ? Please guide us
sincerely,
Zaim.
