TMCS1100: TMCS1100 Bandwidth concern

Part Number: TMCS1100
Other Parts Discussed in Thread: TIDA-010062

Dear Team,

I see TIDA-010062 using TMCS1100 for the PFC current loop control

The PFC stage switching frequency(Fsw) is around 100kHz.

Base on my experienced, the control loop bandwidth need to be 10*Fsw.

So the TMCS device should be around 1MHz to fulfill the job here.

May I know the reason why you choose this device here and the system can still work well?
