Abstract
Embodiments of a circuit and method for generating a ripple voltage for a ripple based constant-on-time DC-DC converter are disclosed. A circuit includes a ripple voltage output, a first charging circuit connected to the ripple voltage output, a second charging circuit connected to the ripple voltage output, a charge control circuit configured to charge the first charging circuit and the second charging circuit out-of-phase from each other in response to an on signal from a ripple based constant-on-time DC-DC converter, where the voltage of the first charging circuit and the voltage of the second charging circuit are provided at the ripple voltage output as the ripple voltage.
