A regulator circuit can include a ramp generator configured to provide a ramp signal, a switch configured to provide input power to a filter, an error amplifier configured to provide an error signal at least in part using a difference between a first reference voltage and an output of the filter, a first comparator configured to compare the error signal with the ramp signal, control logic configured to control a state of the switch in response to an output signal from the first comparator, a second comparator configured to compare the output of the filter with a second reference voltage. The ramp generator can be configured to reset the ramp signal to a specified state in response to an output signal from the second comparator. |
