Method and apparatus for operating a DC/DC converter

A method of operating a DC/DC converter in a continuous-conduction mode (CCM) or in a discontinuous-conduction mode (DCM) to produce an output voltage, the DC/DC converter setting a pulse width modulation in CCM based on a COMP signal that varies as a function of the output voltage, the method inclu...

Zusammenfassung:	A method of operating a DC/DC converter in a continuous-conduction mode (CCM) or in a discontinuous-conduction mode (DCM) to produce an output voltage, the DC/DC converter setting a pulse width modulation in CCM based on a COMP signal that varies as a function of the output voltage, the method including capturing the COMP signal utilizing a digital-to-analog converter at a transition between CCM and DCM, and varying a frequency of operation of the DC/DC converter in DCM based on the captured COMP signal.
