  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.
