Abstract
Methods, apparatus, systems and articles of manufacture are disclosed that facilitate multiple modes of converter operation. An example apparatus includes a comparator configured to provide a first trigger signal to initiate a first pulse width modulated signal in a constant-on-time mode for a power converter, an oscillator configured to provide a second trigger signal to initiate a second pulse width modulated signal in a fixed frequency mode for the power converter, and a selector configured to receive a select signal, the selector configured to output the first trigger signal to a pulse width modulated signal generator to initiate the first pulse width modulated signal based on a first state of the select signal, and output the second trigger signal to the pulse width modulated signal generator to initiate the second pulse width modulated signal based on a second state of the select signal.
