Four half-bridge switchers for about $5. Current and thermal limiting.
I was about to dremel and test my own half-bridge driver, but won't
now. I guess I'll have to shuffle up the abstraction stack.
There must be something cool that these could be used for. A
16-channel power supply?

In that package, they’re probably intended for driving LED strings in >displays, where board space is not a problem.

Half-bridge audio amps can be tricky. At that price, may as well go full-bridge. A half-bridge switcher can pump power uphill, back into
the power supply.
I wonder if we can get our little RP2040 cpu chip to do a multichannel closed-loop supply, and maybe generate spread-spectrum PWM on 8
channels.
