Abstract
Described embodiments include a voltage regulator circuit comprising a first comparator having a first comparator input coupled to a waveform input source, a second comparator input coupled to an output voltage terminal and a first comparator output. There is a second comparator having third and fourth comparator inputs and a second comparator output, the third comparator input coupled to a voltage source configured to provide a voltage representing a current limit, and the fourth comparator input coupled to the output voltage terminal. There is also a state machine having a first state machine input coupled to the first comparator output, a second state machine input coupled to the second comparator output and a state machine output, wherein a state of the state machine is determined by the first and second comparator outputs, and the state machine output provides a PWM signal responsive to the state of the state machine.
