Other Parts Discussed in Thread: LM5122,
Tool/software:
I am making a two-channel amplifier with the TPA3223 (100 W into 11 ohms each channel). It also has a 2-phase boost converter, using two of the LM5122, to create a 36-volt supply from a 12-volt source, on the same circuit board. My circuit setups are pretty similar to the EVMs. As it is in my preliminary schematic, the TPA3223 will run at 480 kHz while the boost converter runs at 250 kHz. Is this likely to create beat frequency problems? Should I sync these together somehow, or allow for it on my circuit board? Can the LM5122 ICs sync to the TPA3223, and how is this done? Thanks - Mike
