Other Parts Discussed in Thread: LM25069
Hello,
I'm designing an AC/DC power supply (115Vac/400Hz - 32Vdc 30W) and i'm trying to use the UCC28780 active clamp flyback using Si MOSFETs.
- Why in the electrical specifications in page 38 in the datasheet, the maximum frequency is 63Hz ?
- What is the conduction mode of this controller ? Is it DCM or Critical conduction Mode ? i can't really understand it because apparently the switching frequency change with the load, what about the duty cycle ?
- How the switching frequency is changing vs load ? same question for duty cycle.
- Knowing that the AC line voltage is 115Vac, what is the DC voltage+/- seen by the transformer ?
Thank you in advance.
Have a nice day.
