TMS320F280037C: Possible configuration for 3.3V analog & digital power supply

Part Number: TMS320F280037C
Other Parts Discussed in Thread: TIDA-01281, SN6505B,

Hi Team,


I’m wondering – what is the most common way to supply analog 3.3V and digital 3.3V? I see and Common Documentation (TIDA-01281) adopts one SN6505B and two LDOs for each. Is it the most common way? Customer is currently using only one DCDC to share two 3.3V rails and considering to switch their design.

Customer is thinking to use 2ch buck solution but I know that our buck portfolio doesn’t have two rails isolation device - Buck converters (integrated switch) product selection | If therere other configurations, can you list them up so that they can review?
