Abstract

A converter circuit includes a power stage circuit configured to convert an input voltage to an output voltage provided at an output, and a control circuit configured to control the power stage circuit. The control circuit is configured to operate in one of a pulse frequency modulation ('PFM') mode and a pulse width modulation ('PWM') mode depending on a current supplied to the output. The control circuit includes a multi-mode timer circuit configured to provide a switching signal to set an off time for each switching cycle of the power stage circuit during the PFM mode and during the PWM mode.
