I am looking for a replacement for the UCC28600 controller in my circuit, since I was unaware that the UVLO is set at 13.8V. I am currently using it in an isolated DC/DC flyback converter with an input range of 10-15V, output 24V @ 300mA. Power supply works fine, just will not start up with a 12V battery. See the attachment for a reference ( yes I am aware that the transformer is wired incorrectly, thanks to you guys!)
What controller can replace the UCC28600 with minimal redesign effort that has a UVLO below 10V or is adjustable? We are making a second prototype anyways, so I don't mind doing some pinswapping or the addition of a few parts. I am just overwhelmed by the sheer amount of available controllers. Thanks for the replies in advance.
