I've not done an inductorless class D before. This will be under 1w of output, run off expensive battery power sometimes, and will be budget critical. The question is what frequency to pick.
What's the lowest frequency one could be run at? What percentage of random small transistors could operate adequately at that frequency?
I'm looking primarily for minimum cost & maximum transistor compatibility, and secondarily for low current consumption. A degree of sound quality compromise is ok, these will be running fairly small speakers.
