UCC24612: Rectification questions regarding noise in flyback SMPS and some other questions

Part Number: UCC24612
Other Parts Discussed in Thread: UCC24636

Tool/software:

Hi,

The UCC24612 can be used in either high side or low side rectification.

High side requires extra parts , and that brings up the question what are the trade offs for flyback where i can use either one.

I suspect the low side version makes more noise on the rectified rail. And in non isolated designs may cause odd glitches when there is no GND return in the case of fast signals powered by different rails.

Is there any documentation regarding the trace offs? Preferably with some examples and numeric values?

I noticed that in the case of the EVAL board presented the values are about the same when it comes to Vout. Tho this is a relatively slow SMPS,  is there another example where this chip is used at a higher frequency?

Also UCC24612-2 is recommended for some topologies but can i use it for the others IF i am not switching that fast?  

I am specifically talking about BCM flyback that will switch at about 150kHz -25kHz .

From what i understand there is also the possibility to drive multiple mosfet with 1 chip, is this correct? ( i will use gate resistors to balance gate current)

Best regards,

Robert
