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