摘要: A mode transition control method and circuit switch a charge pump to an operating mode with lower conversion ratio at a regular interval when the input voltage of the charge pump is detected close to a mode transition point, so as to prevent from misjudgment on the mode transition of the charge pump due to external noise, loading change, or inaccurate equivalent resistance of the charge pump.
