The invention relates to a resonant Dickson converter, a control method thereof, and a drive integrated circuit. At least some of the example embodiments are methods including: driving a voltage output of the Dickson converter by a resonant current through a first branch for a first on time, the resonant current has a resonant half-period; driving the voltage output by a resonant current through athird branch for a second on time, the resonant current through the third branch has a resonant half-period; and then electrically isolating the first branch and the third branch; detecting, during afirst dead time, that the first on time was different than the resonant half-period of the first branch; and adjusting the first on time used in a subsequent cycle of driving the resonant currents, the adjusting makes the first on time more closely match the resonant half-period of the first branch. 本申请涉及谐振迪克森Dickson转换器及其控制方法和驱动集成电路。示例性实施方案中的至少一些示例性实施方案是包括以下项的方法：在第一接通时间内由通过第一分支的谐振电流驱动迪克森Dickson转换器的电压输出，谐振电流具有谐振半周期；在第二接通时间
