Hi Element, TI does not have a low voltage PSR controller that I am aware of. You could do it with a UCC28C41-Q1 device or similar using opto coupled feedback from the secondary side outputs. It would probably be desirable to drive the feedback divider…
Hi Richard
The UCC28C41 has a spice model that can be used as it is very similar to the UC3845 in operation.
I dont believe we have an on-line simulator for this model, you can dowm to a version of PSICE from TI, http://www.ti.com/tool/tina-ti

Hi,
Based on the datasheet back in year 2009, http://www.ti.com/lit/ds/symlink/ucc28c41-q1.pdf , UCC28C43QDRQ1 and UCC28C45QDRQ1 is under product preview. May I know are this two part no available for order now?

Hi Bernard,
Thanks for your reply. The power provided by the flyback converter will be used to power the gates drive of an inverter and a simple buck converter IC, thus the required output current is on the range of 250mA to 400mA.
I have looked at the…
Hi Shahib,
Currently, we do not have a model available for UCC28C45, but we do have a TINA-TI model available for UCC28C41 which has a lower startup voltage. Can you use this one instead?
