Hi Hailey,
Any PWM controller can be used to make a boost or inverting boost converter. See the following application note ( SNVA856B ) on how this is done. The UCC28C50 might be a good solution to make this happen. Without a transformer-based solution…
Hi Aki,
It looks like you need two power supplies followed by an OR'ing controller to support this. The BSR team has several Flyback/SEPIC controllers that might do the job. Our general-purpose PWM the UCC28C50 might also be an option.
Can you confirm…
