Abstract: A time-based DC-DC converter is controlled in response to a first oscillator signal based on a first control signal, a second oscillator signal based on a second control signal and a controlled current based on a feedback control signal. The first control signal and the second control signal are a function of the controlled current. The feedback control signal is generated as a function of the first and second oscillator signals by: generating at least two binary signals including a first binary signal based on a difference between the first oscillator signal and the reference signal and a second binary signal based on a difference between the second oscillator signal and the reference signal; and generating via a charge pump the feedback control signal based on the first binary signal and the second binary signal.
