Abstract
A method includes comparing a ramp signal with an output signal of an error amplifier to determine an initial turn-on time of a boost converter, generating a turn-on time of the boost converter through multiplying the initial turn-on time by a predetermined constant greater than or equal to 1, and maintaining a switching frequency of the boost converter substantially constant through varying a value of the predetermined constant.
