292              mixed PWM/PFM mode, using PFM under light loads and
293              switching to PWM for heavier loads. Forcing PWM mode
294              trades efficiency under light loads for lower output
295              noise. This probably makes sense for HiFi audio related
296              applications that aren't battery constrained.
