Other Parts Discussed in Thread: UCC27800, , UCC28630
Hi Team,
My customer is designing a Flyback-converter (quasi resonant) with the following specs:
Vin 70-920Vdc,
Prim (aux winding) output voltage (I/O isol1500Vac_1min) : 18V 0.7A
Sec output voltage (I/O isol 3000Vac_1min): 18V 0.7A
They are considering the UCC27800 for this design, which is a Quasi resonant flyback DCM. And they would like to know if this device also operates in CCM mode and still delivers the required output power at a low Vin?
If not, do we have an alternative here? Seems like ADIs LT8316 operates in both modes.
Thanks for the support.
Regards,
Obinna.
