Combining metal-alloy 3.3µH inductors along with flow-through
design yields the industry's smallest four-channel automotive
Class-D amplifier size. Figure 5 shows that the TPA6404-Q1
complete solution (including amplifier and all required passive
components) measures just 4.5cm2.

If you need to focus on reducing overall solution size and
the heat generated in your entry-level infotainment head unit
system, then I invite you to learn more details about how
the TPA6404-Q1 2.1MHz Class-D amplifier can significantly
help. You can also reduce the development time with the
TPA6404-Q1 evaluation module (EVM), as well as the
schematics, design files, and layout guidance, to kick-start
your design.
