Part Number: WEBENCH-POWER-DESIGNER Other Parts Discussed in Thread: UCC28C40 , UCC28C50 Hi, I'm designing a flyback topology with the UCC28C50Q controller. I need to run the simulation using a Wurth coil that is not includef to the alternative parts…
I have not implemented a PWM flyback controller in this design yet. I have been trying to drive it directly from my microcontroller. If I need a PWM flyback controller I have been looking at UCC28C50-Q1.
Hi,
Q1, UCC2891 VIN needs minimum 18V to start, if not using VIN, but VDD, it is minimum 13.2V. So for 9V input, you need to add external circuit to make UCC2891 to start
Q2, UCC2800, or UCC28C50
Q3, yes, or use TINA TI.
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…
