摘要
An apparatus configured to control a pulse frequency modulation in a single-inductor dual-output power circuit. The apparatus fixes a pulse width of one of a maximum on-time pulse signal (which is used to define a maximum on-time during which a current flowing through the inductor is generated) and a minimum off-time pulse signal (which is used to define a minimum off-time during which either the boost voltage converter or the buck-boost voltage converter produces a positive voltage or a negative voltage). The apparatus adjusts a pulse width of the other pulse signal.
