In Part 1, we’ll discuss some general recommendations for designing PCBs that use motor-driver ICs, which require special cooling techniques to handle the power dissipation.

Let’s digress for a moment to introduce the four-switch (non-inverting) synchronous buck-boost topology. This circuit is an excellent example to study DC/DC converter PCB layout. It has numerous ...
