Abstract: A boost converter control method includes: obtaining a peak current reference signal; obtaining a current sense signal; obtaining a flying capacitor (CFLY) voltage error feedback signal; and providing switch control signals during a peak current limit mode responsive to the peak current reference signal, the current sense signal, and the CFLY voltage error feedback signal.

Abstract: In some examples, an apparatus includes a constant amplitude ramp generator having a differential output and first and second generator inputs, in which the first generator input is coupled to a power terminal. The apparatus also includes an input voltage feed-forward circuit having a feed-forward input and a feed-forward output, in which the feed-forward input is coupled to an input voltage terminal, and the feed-forward output is coupled to the second generator input.
