280              mixed PWM/PFM mode, using PFM under light loads and
281              switching to PWM for heavier loads. Forcing PWM mode
282              trades efficiency under light loads for lower output
283              noise. This probably makes sense for HiFi audio related
284              applications that aren't battery constrained.
